Re: ESP32-C3-MINI-H4 USB to UART not working Quote PostbySprite»Wed Sep 18, 2024 12:19 am You should short DN+ with DN2+ and DN- with DN2- otherwise your USB-C connection only works one way around; have you tried flipping it to see if it works then?
Small & Medium Development Boards/Modules (Not Using PCB Module) These small and medium sized development boards have USB-to-UART interfaces, but the ESP32 chip is directly incorporated into the board (instead of using a ESP32-based surface-mount module). MAKER MODEL FLASH MEMORY ANTENNA EM...

it is clear that everything is in order with the uart connection and USB-UART works correctly, Actually, what you describe does not necessarily imply that the "TX" direction USB->UART (connected to the UART-RX of the ESP) is working. ("No serial data received" may indicate that the PC...
