ESP32S2 with CH340F custom board not working

Postby antonmeyer » Mon Mar 25, 2024 5:38 pm

Hi,

I just had this board developed and assembled, but when I connect it to my computer it never shows up as a device on my computer.

Does anyone have an idea what I can do to troubleshoot the issue?

Thanks!

On the USB connector, the CC pins should be connected to a 5.1K pulldown each. If you don't have that, an USB-C-to-USB-C cable won't work; it won't give the board any power. To bypass this issue (for debugging), you can use an USB-A to USB-C cable, that won't have that issue.
