Low Level

Espressif IDF is the recommended tool to program ESP32 at a lower level. And it is possible to program over the UART that is available on the programming header of Colibri carrier boards.


The Colibri MCU3 can be programmed with the Arduino IDE. The support for this is provided by Espressif and Arduino.
