In the Wiki in “The first time to use” https://wiki.dfrobot.com/SKU_DFR0868_Beetle_ESP32_C3#target_4 it is written that you should enable “USB CDC on Boot” The boards.txt the CDC on Boot is not on by default https://github.com/espressif/arduino-esp32/blob/master/boards.txt#L6469 https://github.com/espressif/arduino-esp32/blob/master/boards.txt#L6478-L6481
Whats the reason for that?
On platformio i have to define additional compile flags to make it work. There are not lot of boards to compare too: - lolin_c3_mini - Adafruit QT Py ESP32-C3

Hi
For Beetle ESP32 - C3(DFR0868), if you do not enable USB CDC, the serial port is 20 and 21, instead of 0 and 1.
