PMOS开关电路,很常见呀。不过要注意VGS数值不要超过12V
https://whycan.com/files/members/1798/屏幕截图_20240722_122744.png
这个电路有问题,这个GS上并一个这么大的电容,这个PMOS大负载的时候分分钟烧掉

考虑一下新唐 Nuc972df62y 这种半个手巴掌大的封装
消费产品和工业控制不太一样,想做消费产品,你可以把封装做小一点,但芯片价格必须足够低,不然没有市场。想做工业控制用品,就没必要太过追求小的封装尺寸,做好稳定性。工业控制产品溢价率比消费品高很多,如果你做得跟消费品一样还怎么溢价。

已经打样出来了,没有测试
另外如果有想打样简单板子的朋友可以来找我
手头几张JP的免费券,可以给坛友打
另外,我给楼主打的板子你收到了吗,测试了嘛@saub
不好意思,最近比较忙,还没时间焊接板子

华大的HC32单片机还不错,性价比较高,在当前STM32单片机价格暴涨的情况下,是个不错的替换方案。
缺点是资料太少,下载接口不兼容SWD,所以分享一个官方的CCID下载器PCB图纸和固件,此下载器可以实现离线编程,使用比较方便。

孤星泪 说:看下linux的启动日志,有没有生成mtd分区。如果没有生成就是驱动和配置问题.
谢谢,刚刚解决
原因还不太不太理解 “这种情况是因为mkfs.ext4的时候制定的参数,旧的内核不支持导致”
方法如下:
1:读卡器插入SD卡
2:利用Gparted软件先取消rootfs的挂在
2:终端敲入tune2fs -O ^metadata_csum /dev/sdb2 (根据rootfs的分区选择sdb1,还是sdb2)
3:提示:请在这个文档系统上运行 e2fsck.
4:敲入e2fsck -f -a -v /dev/sdb1370 个已使用的inode(0.02%,总共 1896832) 0 个不连续的文件(0.0%) 0 个不连续的目录(0.0%) # 一次/二次/三次链接块数:0/0/0 Extent深度直方图: 76 163787 个已使用的块(2.16%,总共 7573504) 0 个坏块 1 个大文件 41 个普通文件 34 个文件夹 1 个字符设备文件 0 个块设备文件 0 个队列文件 0 个链接 285 个符号链接 (285 个直接符号链接) 0 个套接字文件 ------------ 361 个文件
5:查新插入sd卡 就可以正常启动了
