Nordic nRF52 和 WCH CH58x 系列均支持蓝牙 5.0 以及 2Mbps 传输速率。 nRF52 有一个有趣的例子——nrf52-ble-image-transfer-demo ( https://github.com/NordicPlayground/nrf52-ble-image-transfer-demo )。 nRF52模块在淘宝上很常见。然而，除了功耗成为问题的情况外，可能还应考虑其他连接解决方案。

@mysteryli

我与DigiKey等一些美国分销商有问题。他们宣传免税送货到保加利亚，但当包裹到达时，运输公司 UPS 会收取费用和税款。我不得不说，来自美国的包裹到达得更快。组件价格较高，但考虑到在中国我支付许多交易，运输和海关费用，它变得相对相同。我已经在中国购买的一些由中国公司制造的组件，如Anlogic FPGA，Allwinner产品等将没有用处，这是损失。

@bigbigcong

你是对的。不幸的是，从中国运输产品的问题来自多年。我已经联系了多个欧洲和中国当局 - 没有采取适当的措施。事实上，在欧洲，有人说，这是保护美国企业的唯一途径。但是中美关系我应该关心什么呢？我每次购买都要向淘宝支付3%的交易费，除此之外，最近淘宝将交易货币改为美元，所以我也必须支付货币汇率。包裹延迟了几个月，在某些情况下甚至没有收到......争吵，不得不说我与中国的交往即将结束。

@gjc2010gys 以下列表没有步进或 BLDC 电机，出口此类项目应该不是问题。一些淘宝卖家过去曾经向国外发货。但目前没有人同意。这不是快递公司的问题，而不是一些误导的中国海关政策。联邦快递，DHL是极其昂贵的公司，因此使用中国产品值得怀疑。例如。我以 123.39 美元的价格购买了 Hantek 6074BC 示波器，如果我必须支付 100-200 美元的运费，我可以在欧洲购买使用泰克 4 通道 TDS224 的价格，价格约为 220 美元。集成电路也是如此。USB 3.0接口CH569的成本约为5.40美元，FTDI FT60xQ-B – 8.40美元。考虑到我在大约 4 个月前支付了第一个包裹，但仍然没有收到，我真的怀疑是否会从中国订购任何东西。

@gjc2010gys

该软件包没有任何问题。主要是电子产品 – 电阻器、电容器、集成电路、一些 FPGA、SoC – Allwinner T113、电路板......还有一些3D打印机部件 - 车轮，轴承以及他们可能认为有问题的东西 - 很少有步进电机。但是这些电机的磁铁非常小，我真的怀疑它们是否会带来任何安全问题。事实上，几个月前，我购买了相对较小的 BLDC 电机——运输公司拒绝发货。我不得不退回并从速卖通购买。

The response I received from China customs:

您好：
   您在中国海关门户网站业务咨询栏目提交的关于中国海关不断退回我的包裹的问题，现回复如下：
        您的留言已收阅，请将该问题提交网站业务咨询栏目处理，或请拨打12360海关服务热线，那里将有专门人员为您解答或处理。

It is interesting why the Chinese authorities – China customs, China Ministry of foreign affairs have no proper contact information: email etc.

So, US shoot down the Chinese 'spy balloon' … If you want a war you will get one.

@哇酷小二

很不幸全世界都有像你这样的人。你不是在寻找解决问题的方法，而是在侮辱。在中国有值得关注的产品，比如乐鑫、WCH等的产品。但是欧洲和北美的许多开发人员拒绝与他们合作。直到现在我都支持中国产品，这肯定会改变。另外，淘宝whycan.cn店铺的产品价格不菲。还有其他商店价格更低且免费送货。

@gjc2010gys

Currently China customs is returning the packages without clear reason. In my opinion, probably they have lots of corrupted officials waiting for bribes. Apparently Chinese selling to other countries via other sites, have no problems sending goods abroad.

Many of the product on the European market are Chinese made. Just the prices of most of them are few times higher.

@农夫三拳

你是对的，我买了很多不该买的东西。这将会改变。至于其他问题，你应该先批评自己，再批评别人。中国对维吾尔族穆斯林的剥削情况如何？

@IOsetting

My current problems are associated with shipping. The last package that seems to be returned:

Otherwise the shipping company has strange pictures:

Have you ever checked the prices on Aliexpress ? The price of some items is 2x, 3x … higher. For example just look for Sipeed 荔枝糖 Lichee Tang Nano1K 极简 FPGA 开发板 直插面包板  - ¥42.00 on Taobao, ¥98.00 on Aliexpress etc.

是否可以将 CVBS TVIN ADC 用作标准高速 ADC？最大采样频率可能是多少？

Taobao is really getting worse. The latest – transaction fee and they charged me in USD.

By the way I will really appreciate if someone can share the FPGA firmware for Hantek 6254BC oscilloscope. One topic on EEVblog - Hantek6074BC-hack to 250MHz, states that the boards of 6074BC and 6254BC are the same, just the FPGA firmware is different.

全志T113-S3是商业产品， MA35D1是工业解决方案。

For some time, I had no serious issues with shipping products out of China. BLDC motors were in general problematic … However recently the export issues started again. Have one package it was returned multiple times. Is this currently common in China ?

You will not win, Ukraine and Russia are the same country. Just Ukrainians are poor and brainwashed by the West. It would be better if Ukraine surrenders.

我最近遇到的中国产品的问题是，购买了1W激光模块，工作了12-13个小时，然后就停了。我从其他论坛上了解到的情况对于中国激光模块来说非常普遍。

https://item.taobao.com/item.htm?id=594984044926

I do have other views: apparently some companies got “exclusive” rights to ship abroad and there are problems …

I should also mention the fact that the package in dispute was not received.

For anyone that purchase anything from China – you might may pay for something, pay expensive shipping via DHL Express …. and receive nothing. The Chinese government does nothing about the raised issues etc.

Dealing with China is just loss of money, time, resources … to mention not the insults etc.

No, that is some other project, seems based on RaspberryPi.

Thanks for the reminder. You know in Europe, … Bulgaria there are quite few Chinese restaurants. In many cases they do not comply with the local health requirements and are subject to various penalties. I usually do not eat at such places, the last time my relatives brought food from a Chinese restaurant, it was so hot, the plastic box was melting into the food … so, actually the Chinese are provide bad and unhealthy food. The mater with the Chinese in Europe …, their activities apparently needs to be further evaluated.

The last time I checked the Huawei equipment will be removed from the UK telecoms. If you intend to get the same result within Europe … continue in the same direction.

Despite politics for more restrictions, nothing in common.

Some Chinese are crooks and dishonest people. The last package from Shipforwarder was returned to them and currently they even do not respond to inquiry where the package is.

The Europeans are very stupid people, making an investment deal with China …

No benefits … just problems and losses …

Apparently those products poses security threats to European and US customers.

U.S. strikes at a Huawei prize: chip juggernaut HiSilicon
https://www.reuters.com/article/us-usa-huawei-tech-chips-analysis/u-s-strikes-at-a-huawei-prize-chip-juggernaut-hisilicon-idUSKBN22X2T3
….

I am not happy at all with any products from Hangzhou Xiongmai Technology Co.,Ltd. The modules I tested worked for about 2 years and presented various defects, to speak nothing about the technical, software ... issues etc.

In UK for example people loose their jobs … for such comments … Unfortunately, in China as well as the moderators of this web site seems not to take proper measures regarding the previous as well as current insults, harassment etc.

I currently wondering which would be more effective, to demand from the European authorities this web site to be ban in Europe, North America or take more drastic measures ?

The Chinese greediness is endless. Not only the shipping cost were raised, different fees introduced, but the lattes: The earlier advertised PCB manufacturer, raised the price, for 2 model PCB – 20 CNY/10 pcs., for 4 model – 120 CNY.

If you have to pay just for shipping 30 USD/kg would you still find it laughable ?

The latest Shipforwarder price for shipping 1 kg package to Bulgaria:

I am sorry, but really do not understand what you are trying to prove. The facts show something different.

For example, recently I ordered some ICs (30 pcs - MT3608 丝印B6289 SOT23-6 5V/1.2A 移动电源专用芯片), the Shipforwarder company claims their weight is 40 g., presenting the picture:

I got s similar bag and put some similar items, just to see what the weight might be: 4g.:

Shipforwarder claims that the items weight is 40 g. while the actual weight (probably around 4g.) is much less.

I use: https://item.taobao.com/item.htm?id=9379760689

20 CNY for 10 pcs. (2 layer, max 100x100 mm) and they give me some small bonuses.

I do not get along with Olimex. Some years ago I was telling them to developed a cheap Linux board, when the CHIP board was announced:

They got angry at me and responded that they where not going to developed single core Linux board, since the 4-core SoCs were cheaper. The price of 9 USD was impossible to maintain etc. But in your opinion do the international customers care whatever Olimex wants, since they can purchase sub-10 USD Linux board, like Orange Pi,  Lichee Pi Nano, Zero ? Can anyone state how many single-core Linux boards with Allwinner F1C100S, V3S … were sold since 2015 ?

In my opinion, it is not much about infrastructure, rather than US protectionism demands. They push China to raise the postage and shipping fees, so the US products can be competitive. The only thing is that US and Europe are technologically failing much behind China and they can not offer such products. You know what is funny, the European Union invested billions of Euros (tax payers money) in Artificial Intelligence and Europe has no major players on the global market. There was one very perspective Romanian company called Movidius. To the best of my understanding the European Union gave them hundred of millions in grants for developing new technologies. And the company was sold to Intel. Intel did noting, but developed some computational stick. I’m currently waiting for respond from one French company, called GreenWaves Technologies (https://greenwaves-technologies.com/), they manufacture GAP8/9 - IoT application processors. One of the problems is that it has small internal memory. It is expandable via HyperBus. Do you know what is the price just of a memory chip with HyperBus ?

As about the fakes and low quality products on TaoBao. I had quite few such experiences.
Recently purchased some SPP-C modules:

They were intended for communication with smartphones. But some communication errors were appearing. I had quite a quarrel with the Android software developer, he was demanding that the modules are fake and providing unstable communication. The dispute got so heated, huge insults … at the end, the forum administrators deleted the topic … and I throw on the garbage the boards … So much time, money lost for developing, preparation … Well I do not think that Beken (http://www.bekencorp.com/) BLE products are so bad, but I was considering to order some Nordic Semiconductor (https://www.nordicsemi.com/) BLE boards too. By the way is there Beken IC fakes ?

In the past many TaoBao stores were willing to ship to Europe directly, currently no one is willing to ship directly.

You mean in the past or currently ?

In the past: semiconductors, components, PCBs., motors, 3D printer parts, various welding accessories, IP camera modules etc.

Currently, I have not purchased anything yet. I was thing about ordering some PCBs, again semiconductors, capacitors, resistors, probably some PCBs. I was also considering getting one Kendryte K210 EVB and few modules. In your opinion, which option is better: Widora’s BITK210, Sipeed MAIX Dock K210, Allwinner R329, other MCU/SoC with AI ? I spoke lately with Allwinner about R329. I will not be available for at least 3 months.

35 CNY for X3 - looks expensive. The price of H2+ is 14 CNY ?

What SoC you use in MangoPi 1S ?

Come on … viruses, West vs East … don’t you have fun in China ? I am considering F1C100S for one product that I would like to behave like Jexy (https://www.imdb.com/title/tt9354944/). Other solution: Allwinner R329, HiSilicon Hi3516DV300 … ?

I have currently an inquiry for something similar, but it requires high reliability.

Initially, I was considering ESP32, various audio apps have been ported such as The ESP-Voice-Assistant SDK (https://github.com/espressif/esp-va-sdk), but currently looking at Realtek IoT products. Realtek has both IoT Control (https://www.realtek.com/en/products/communications-network-ics/category/802-11b-g-n) and IoT Video (https://www.realtek.com/en/products/communications-network-ics/category/iot-video) products.

I have not tested extensively Allwinner V3S but probably something like Atmel ATSAMA5D225C  (https://www.microchip.com/wwwproducts/en/ATSAMA5D225C-D1M) might be preferable.

You do not seem to have proper understanding about the North American engineering regulations, laws etc. When I was in Canada there was created one program for internationally educated engineers, so they can learn those stuff. But have to say to the best of my understanding the Chinese engineering education apparently is not good ...

I like nationalists, I do not like people who pretend to be something they are not. For example I was looking some time ago at some Chinese dressed as ancient Roman members of the parliament. I do not think there were such people. On the other hand, I was looking few days ago a film about Marco Polo. Can you say the Europeans had strong influence during the development of China ?

BBC, IMO is more like documentary, probably you would have to wait a bit …

I doubt that it will, it is a business. Furthermore the communist ideology, it is not yours. You seem to miss the fact that Bulgaria was part of USSR, I lived in those times … Also what communism you talk about ? The Chinese businesses are greedy as hyenas. I was reading recently about a case, a Chinese girl passed away because of hunger, collecting money for his ill brother treatment. The Chinese actually collected the necessary money for the medical treatment, but after the girl’s death and the publicity of the case.

In Canada some say a person have to love what he/she is doing. Why you consider just profit ? The stuff a person works suppose to bring enjoyment etc.

Sure, but as I stated, I am not charity and expect refund of my money including compensations etc. By the way the comment above refers also to all your Chinese junk products … on our markets.

@OggyJFX , Quite agree with you regarding the jink Chinese products and the crook Chinese businessmen. Still the board was sent to me. As mentioned in the other forum topics, I was willing to give it for free, no one was interested. If you interested about it, I can ship it to you ?

As about Huawei, there are very serious concerns in Europe regarding this company. I was reading few days ago, the French financial minister was complaining that this company was potentially blackmailing the French government, by promising to open a factory … Probably you are aware how Huawei got the 5G contract in UK – granting to some UK royalties contracts in China etc.

Not really interested about dealing with Chinese products, still I have some CPUs, MCUs … like Allwinner V3S, ESP32 … if you refund the money I payed for those items, sure, will not bother you with those matters.

@Blueskull, It seems you do not have understanding what troll means, probably you should read more before using foreign words:
Troll - https://en.wikipedia.org/wiki/Troll
Internet troll - https://en.wikipedia.org/wiki/Internet_troll

….

As about the complains, currently the ship-forwarding company – YoyBuy demands money … In general, many Chinese do not understand it, but depending on the jurisdiction - if goods, products not delivered on time - no money.

By the way, what is the situation with the corona virus, disinfecting packages purchased from TaoBao ... ? I was reading the Chinese government started to disinfect the money in China.

@cityf, Quite agree. Still, there is this package that is held in China. It has items that I paid for: 3204.27 CNY. In addition, I paid about 150 USD shipping fess . Please refund my money !

@daydayup, actually, nothing interesting. I’m watching these days the 李子柒Liziqi Youtube Channel: https://www.youtube.com/channel/UCoC47do520os_4DBMEFGg4A, the latest video: 当腊味煲仔饭遇上胡椒猪肚鸡你又以为有故事？还是没有！ (https://www.youtube.com/watch?v=3mCeQLqB7TQ), very similar traditions. There are some differences in the cuisine thought.

演技担当黄晓明, The Google translate makes the translation from Chinese to English not understandable.

小智, As stated earlier – the meaning of “get out and fuck off” is insulting. Please do not use it. There is no such thing like Народна република България – People’s Republic of Bulgaria. This name was used during the communism but currently Bulgaria is a member of the European Union etc.

I wold like to thank you to all of you for your comments. Establishing that some of the Chinese products might not be suitable for the Bulgarian market etc.

@ 好想做个有钱人, No, the question is about achieving mutual respect, avoiding conflicts etc.

@ 路人乙, Chinese companies want access to European, North American … etc. markets. If you can not provide the same level of reciprocal access and investment protection, such can not be provided to your companies. As much as I am aware some Europeans want access to the Chinese market, establishing European banks in China, our shipping companies etc.
Also the problem with the Chinese crook businesses, such as ship-forwarding companies. In the past even 晕哥 tired to speak with one of them without success. In Europe we have tools to deal with such companies – government agencies, consumer protection organizations etc.

@hzqlz,

I am not much knowledgeable about Buddhism, but on Internet what I found:

Buddhists have to make themselves aware of the damage they do to the environment so that they can then act to change it.

Correct me if I am wrong, but isn’t China is one of the biggest world environmental polluter ?

The name Mitko is a short form of Dimitar. It is rooted in the Greek goddess Earth mother Demeter, who is rooted in the ancient goddess Earth Mother. The short form Mitko is used just by friends.

There is currently global warming, trading and other types of issues with China ... I do not consider China my friend, neither there is any trend in direction of improving the situation.

There are laws: engineering, trading … since you continue to demand that those laws should not be followed, the environment issues … not considered, I would like the account to be deleted.

@KfAnr , Actually, it seems you might have a better use of this board than me. It was provided to me from zhenfanhei for free. Assume he would not have anything against if it is given to you. Schematic:  hq_050ips_v02.pdf

If you are interested I will arrange the shipping to you.

Aliexpress services are horrible. The last time I made an order from Aliexpress I waited about 2 months to receive the products etc.

@savebox, It is, but what is poorer: Got a message today from the ship-forwarding company, they continue to attempt tricks …

@迪卡, Not so sure what is the reason 晕哥, not to want to close the account. There is some misunderstanding, he thinks I am a teacher at some university, which I am not … I do not have much deeper knowledge about the Chinese culture … In India, it has been said that if a story doesn’t end well, it has not finished yet. How about China ?

@netwp, When I studied Chinese, I had a dispute with one of the teachers about the meaning of white tiger in Chinese. I probably do not have to explain what its commonly referred in China, but it does have other meanings too ...

@LinjieGuo,

In Bulgaria, there is a very well know story, about a local banker that was tricked by some foreigner who tough can make easy money, do not comply will local customs etc. The Bulgarian banker released a wave of discrimination against the foreigners and the case was settle.

Racism is a tool to keep people who are less educated about a state laws and rules … on their place.

I might loose couple of hundreds of euros, but you going to loose billions.

@smartcar, this is a problem associate particularly with the ship-forwarding companies. So far I tried 3 companies – all crooks and liars. Twice lost the items I purchased … they extorted me to pay for something that suppose to be free etc.

The latest, I have in a Beijing warehouse packages that weight about 14.300 kg. This crook company called YOYbuy established that after packing the total weight of the package is 19 kg. Almost 5 kg – packaging materials !!! Also they want money in advance …

From some of the post and behavior of the forum, I do understand that some Chinese think that they can do crook activities, involved with such unethical business practices and we the dumb Eastern Europeans have to pay you ?

I inquired many times the Chinese government, even the Chinese police they did nothing about the issues.

Although China has 1.3B people, the whole world is much bigger and would like to assure you that proper measures can be taken against China.

我在他们那里有一个帐户，但是已经丢失了。目前，它要求在中国通过中文电话号码进行短信验证。我可以使用任何短信信箱吗？

Sorry, Google translate makes strange translations.

I have an account with JLCPCB, but there seems to be an issue with payments via credit card etc. Also the shipping they use in China is just SF courier service?

Yesterday and the day before that I looked at Taobao. The initial offer I had for 102x72 mm 2 layer standard PCB was 66 CNY. Later, I got an offer 20 CNY (8 CNY shipping) and I submitted an order. But notices some things that needed to be fixed. However today the seller is not willing to update the board. According to him, it was already submitted for manufacturing.

Also to the best of my understanding the JLCPCB price for such board is around 2 USD ?

OpenWRT支持某些ADSL调制解调器。因此它们仍然可以使用，但是配置/安装OpenWRT是一个耗时的过程。

Marlin固件仍未移植到STM32H7。

我今天尝试用shipforwarder.com解决问题。关于他们声称PayPal撤回资金，以下是PayPal的回复：

In relations to these two payments, I can confirm that we have not withdrawn any of these payments, and no money has been refunded. To prevent problems with merchants shipping from China, please make sure to properly review the website and investigate what country they ship from.

不好意思，但上面的产品被这家骗子中国公司封锁了。

不幸的是，我试图找到另一家航运公司似乎不成功。我目前遇到与Yoybuy.com类似的问题。他们在实际确定包装重量之前需要钱。

正如您可能从主题中注意到的那样:https://whycan.cn/t_2021.html，我遇到了财务损失，因为shipforwarder.com。我有一些抱怨，因此www.shipforwarder.com说我收回了我的账户并阻止了它。我的仓库里还有以下物品：

我不喜欢浪费，我愿意免费将这些物品交给任何有兴趣的人。该人必须向中国境内的shipforwarder.com支付运输费。如果您有兴趣，发布消息，我会联系shipforwarder.com。

@smartcar，你是一个非常傲慢的人，但我也认为我真的在这个论坛上浪费时间，同时继续浪费我与中国骗子打交道的时间。

@晕哥，请删除我的帐户我不想与中国有任何关系，也不与任何中国事务有任何关联。

我不认为正常，首先显示的价格为32元人民币，之后为34元人民币。但根据你的回答，我得出的结论是，我根本不应该与中国打交道。许多中国人都是对交易行为，法律等有非常不了解的骗子。

你能发布一些初步图片吗？

我仍然更喜欢MT7628DAN，WiFi连接被宣传为2T2R 2.4 GHz，具有300 Mbps PHY数据速率。

eCos  - 维基百科：eCos附带的FreeBSD TCP / IP网络堆栈已过时（大约2001年），并且系统暴露于众多安全和稳定性漏洞（FreeBSD RELENG 4 4 0 RELEASE for IPv4和FreeBSD来源KAME for IPv6）。官方eCos维护者似乎不会监视FreeBSD或KAME的安全性或稳定性更新，而是依赖于eCos用户的最小和不足的错误报告。

MT7688 eCos端口可供下载吗？

我无法找到有关BIT3.1的信息，也在淘宝网上只看到BIT3似乎可用。更多信息 ？

我也无法在淘宝上找到MT7628DAN。

@mango, 我收到一条评论说F1C100S是一个无用的垃圾。 ARM9是一种旧架构，对裸机编程，Linux, RTOS等没有适当的支持。

至少你考虑过包括WiFi模块吗？您打算以什么价格出售这些模块？

它们既不完全兼容，也不便宜。 STM32F103RBT6是4.63￥，我支付GD32F103RBT6  -  6.67￥。
我有一些代码使用GD32F103RBT6无法正常运行。当被问及GigaDevice注册差异手册时，他们甚至没有回应。 GD论坛也没有信息。有关GD32的任何参考和从STM32传输代码？

我避免与乌克兰人打交道。给我带来了经济上的损失。他们有很多犹太人，在与犹太人打交道时，没有任何经济利益。你非常误导你可以嫁给欧洲妻子50欧元，甚至是一位老太太。据我所知，这些东西至少花费20000-30000欧元。你考虑过劫持一个加拿大人，他们会更便宜。在欧洲，我们是种族主义者。英国人更好，他们的外交部长有中国妻子，他们似乎对种族主义问题更严格。

我没有购买第二个。对我而言，这实际上不适合我。我有很多教育，如果我需要它，可能会为我自己做。但我的亲戚坚持购买已经制造的东西而不是花很多钱。他的选择是购买中国制造的。你知道什么是有趣的，与中国卖家交谈，他在中国给了我一些电话号码来打电话和获取技术信息。但是，当我告诉我的亲戚学习中文或送儿子到中国时，他们不愿意。满足人们的欲望是非常困难的。

SF空气 - 价格过高的服务。通过DHL从德国到保加利亚的此类物品交付价格约为10欧元--80元人民币。

通过贿赂，不遵守法律，窃取技术等我可以称之为他们。对不起，你对正义和法律问题有错误的理解。不知道为什么美国，欧洲已经开始采取措施对付许多中国企业。

谢谢，我发消息给卖家。没有这样的选择申请退款？

不同意你 - 这是勒索。对中国游戏不感兴趣给我带来经济损失。

你太对了。我开始取消我打算在中国购买的所有商品。

即使是昂贵的服务，如今SF仍然没有将产品交付给卖方。

我目前正在协商购买此型号的条款：

3in1 Schweißgerät DIGI Pro TMC-205P WIG TIG + E-Hand + Plasmaschneider Inverter

汽车和质量：保加利亚曾经是苏联的一部分，我们的质量很好。看过最新的俄罗斯Lada XRay：

LADA XRAY -Review XRAY

抱歉我的中文，只在清华大学上了一门中文课程。
这实际上是卖方的错 - 我曾三次要求他取消交货，他没有这样做。
关于中国文化，如果中国人想要出售给欧洲，强烈建议他们开始遵守一般贸易原则，包括欧洲的消费者法律，并提供适当语言的文件和手册等。
关于中国文学 - 当赤壁之战发生时 - 公元208-209？在我们的地区，特洛伊战争是在公元前1194年至1184年。保加利亚与马其顿，希腊，土耳其等人有着共同的历史。如果你认为中国人有一些有趣的故事，可以与奥德修斯，阿基里斯，赫拉克勒斯，亚历山大大帝等英雄竞争，那将会很有趣。

这位名叫Shipforwarder的中国骗子 - 要求他们支付40美元只是为了退回产品。

您能否告诉快递公司名称需要在淘宝网站上填写退款信息？

谢谢。这似乎是另一个中国骗子的事。我确实阅读了这些条款，这个地方没有运费。我也确实要求他们不要接受送货 - 他们这样做了。

我确实要求更便宜，但这是他们可以提供的唯一运输方式。

你知道这种来自中国的交通工具和一些中国人打交道很成问题。中国公司是否考虑将其制造服务转移到欧洲附近或附近？

我无法找到这样的服务。我有的选择：

在shipforwarder.com办公室。看看我们有什么对话：

是。谢谢。当我搜索没有显示那些项目时，这很奇怪。

谢谢你的建议。该内核有效，但初始化有点慢：

您还拥有3.3 V，1.8 V和1.2 V的V3S最大功率电流 ?

更喜欢真正的以太网端口。

任何准备好的U-boot +内核包括：Licheepi Zero Ethernet适配指南 ?

是。坏电容C60。

PCB显示R45，C60位于上方。

没有以太网端口。任何支持以太网的内核？

没解决。我们最后一次使用Paypal，但他们的交易费用很高。

我没有看到连接器LED在PCB上有焊盘。
是的，运输大约需要15天。DHPay存在问题 - 信用卡付款。似乎他们没有修复它，所以另一个问题等。

我向SUNXI Linux小组提交了一个关于USB支持的问题。还在等待回应。

我知道这个人 - bunnie.
他开发了一种基于的产品i.mx233。Freescale i.mx233 - USB存在问题 - 性能低等

遵守GPL符合许多中国公司的最佳利益。可以解决和修复许多问题和问题。

在制作电路板之前，确保芯片具有适当的规格等非常重要。但是确定制作定制板是必要的。

你见过新的Allwinner V5主板：Lindenis V5 人工智能视频处理开发板 全志V5 4核A7 4K 360

看来他们的SDK也支持V3和H3。http://wiki.lindeni.org/index.php/SDK_Download_and_Build

与淘宝的LicheePi商店联系，但似乎出现了一些问题。我之前有一些关于Zero的建议，至少可以让相机GPIO电源可以切换，他们并不在意。
我可以购买任何其他V3板吗？如果一切正常，我会自己做。
顺便说一下，你能通过UART实现最快的通信速度是多少？使用H3时，最大值为150000 bps。

任何人都可以在论坛上下载和发帖：compiler-gcc6.h。没有与微信的关联。f1c100s的内核3.10  .config文件？

Debian 9

主线Linux内核存在问题，USB端口无法正常工作。连接器问题？任何观察？

你能试试至少一件吗？如果只是振荡器焊接问题，想知道是否应该购买更多。
