DIY project

M5stack provides “m5burner” with a number of freely available firmwares to turn your m5stick s3 into a voice assistant, hacking tool, etc: m5burner

It is also quite easy to build your own firmware, using whatever framework you like (arduino, ESP-IDF, MicroPython) etc.

Slawomir will release his BLE hacking tool which runs on our badge during OrangeCon!

M5stack provides a good intro as well: M5 stack documentation.
