Raspberry Pi Pico & Pico 2

The Raspberry Pi Pico series includes boards based on the RP2040rp2040A microcontroller chip developed by Raspberry Pi, featuring dual ARM Cortex-M0+ processors. and RP2350rp2350A microcontroller chip developed by Raspberry Pi, featuring dual ARM Cortex-M33 or Hazard3 RISC-V processors. microcontrollers, designed by Raspberry Pi in the UK.

info

Only the Pico W has WiFi/BLEBLE (Bluetooth Low Energy). The default wireless connection between a node and a phone client. capabilities. Meshtastic supports WiFi on the Pico W (although no web server and HTTP API), but does not currently support BLEBLE (Bluetooth Low Energy). The default wireless connection between a node and a phone client..
