ESP32-C3-MINI-H4 USB to UART not working
Posted: Tue Sep 17, 2024 5:25 pm
Hello!
I designed a board with a ESP32-C3-MINI-1-H4 and a USB to UART connection to use Arduino.
My board isn't recognized by USB and I wondered where things might be wrong.
I have switches to EN (pin 8) and to GPIO9
GPIO8 measures HIGH
GPIO2 measures HIGH
GPIO9 measures HIGH and switches LOW
ESP_EN measures HIGH and switches LOW
The ESP32 measures a solid 3.3V.
Thanks in advance!
