FAQ – Frequently Asked Questions
ESP32-C6-EVB appears to connect and disconnect via USB, and some of the relay LEDs are blinking. Is this normal behavior?
Yes, this is expected behavior when the board’s memory is empty. To force the board into upload/bootloader mode manually:
- Press and hold the BUT1 button
- Press and release the RST1 button
- Then release BUT1
What software should I use to program this board?
ESP-IDF or the Arduino package for ESP32.
ESP32-C6-EVB doesn’t seem to send data via the serial port?
The board uses built-in USB OTG. Make sure USB is enabled for CDC communication in your software. For example, in the Arduino IDE, you can enable USB CDC from the "Tools" menu.
