[clennpillo]

hello, when I choose to buy ESP32 board, I found the link given in the article didn't specify the serial port type, say there are two types in the link, CP2104 and CH9102, which one should I buy ?

thanks .

It shouldn't matter, those are just the usb --> uart chips they use. Both should work exactly the same.
