开源自己设计的V3S实验板图

搞了十几年单片机了,现在开始学Linux。全志的芯片便宜又好用,但是没有合适的开发板来学习。买了一个某水果派,板子实在太小了,复位按键都没有,买回来需要先自己飞线才能进入FEL模式下载程序,每次下载还要来回插拔USB线。搞不懂为什么现在各种派的板子都在向着尺寸变态小的方向去卷,小得用起来实在是太难受了!
      自己平时硬件做的比较多,画个板子不难,所以就有了下面的这个设计。

PCB预览图
V3S.png
pdf格式原理图
V3S.pdf
KiCad 6.0版本的工程文件
V3S.zip

      刚刚画好就开源放在这里了,还没去打样。头一次做这个设计,还不知道图纸有没有错误,各位看官如果发现问题,欢迎随时指出来。所有的原理图符号PCB封装都是自己画的,业余时间断断续续搞了半个多月。这几天再研究一下代码编译,弄得差不多了再考虑板子打样。
      PCB是0.15mm的线宽线距,0.3mm内径0.55外径的过孔,2层板就没有考虑阻抗那些参数了。板载2.4G PCB天线,板载CH340N串口。
      各种接插件的品类比较多,所以PCB板上我标注了一串编号,用这个物料编号可以在大家熟知的元件购买平台搜索到资料和图片,这样大家就能清楚我的PCB板上所用的接插件规格,这个可是我画完图之后又花时间在元件商城里一个一个地找出来的哦!

      存在的一些疑问:
      1,RTL8723模块没有找到手册资料,参考了一些开源作品的电路图,但是各个图上关于此模块的连接有一些差异,除了SDIO之外,其它引脚该怎么处理合适?希望WIFI和蓝牙功能都能用起来。曾想到了把未知的引脚连到V3S的IO上,但V3S的IO已经用完了,没有多少空余的分给RTL8723模块了。
      2,摄像头以前完全没搞过,也没到手册参考,不知道CSI接口摄像头的引脚如何排列,所以弄了个排针。另外 VCC-MCSI该接什么电压?3.3V合适吗?看不同的图,这个引脚的电压值也不一样。

Re: 开源自己设计的V3S实验板图

一般主流都是树莓派一样sd卡烧录吧

不需要蓝牙音频PCM不接可以,也只有S3引出了I2S

其余蓝牙就是普通串口

VCC-MCSI取决于摄像头的IO供电

Re: 开源自己设计的V3S实验板图

画得挺好的,学习了。
请教下,RGB交换后,进到linux后如何调整?
TF卡的引脚在器件底部,如何焊接?

屏幕的R和B可以互换,参考这个帖子:
https://whycan.com/t_7335.html

TF卡座焊接不难的,先给板子焊盘上一点锡,然后用热风枪吹,焊锡熔化了之后立即把TF卡座放上去,再稍微吹一会并且对准位置就可以了。我也是头一次焊接这种封装的,第一次就成功了。

Re: 开源自己设计的V3S实验板图

拖拖拉拉,自己玩得太慢了。图画好了之后,还没等到去打样,全家就都变小羊人了,休息了三周。

      先打个样,做个无铅的板子吧,这么多年一直做硬件,感觉含铅的焊锡摸多了要伤身体 sad ,尤其是这种开发板焊完了还要调软件,要来回摸很久,所以选个无铅的。JLC的无铅喷镀要加钱,发现捷配默认就是无铅工艺,这个正合我心意啊!研究一番发现捷配也做了EDA软件也有元件商城,感觉现在这个行业是真卷啊!
      板子做出来这个样子,完全免费的,运费都没出,感谢捷配!

      找个风和日丽的时间打开门窗开焊,防止助焊剂的烟味呛人。先焊电源部分,焊好之后测一下各路电压正常,再焊主芯片及其外设。焊到下面这个样子就可以上电试一下了:
2.jpg
      sunxi-fel正常识别到芯片,证明板子没问题。
      CH340N和液晶屏FPC插座还没买回来,先飞两条线到串口焊盘,先临时测试一下吧

      烧录一个荔枝派的测试固件,正常启动。头一次用KICAD制图,头一次做V3S的板子,没翻车,挺好。
      启动目志如下:
