[ThotAlion]

What MCU would you like Luos to be compatible with?
RP2040

Link the datasheet of this MCU:
https://datasheets.raspberrypi.com

Describe your project:
After several tests on RPi Pico, Pico W and Arduino Nano RP2040, this chip appears as very powerful with a classical architecture (M0 cortex *2). The advantage of RP2040 with respect to others ESP32 or SAMD21 is the price and the big community of Raspberry Pi behind.
Dedicated, in the future to education.

Describe the electronic board hosting the MCU:
