Do you want to know how to connect two Raspberry Pi Pico's together using UART/Serial? This will work on any pair of MicroPython devices.

UART communication can be a bit fiddley, the new library used in this video will make this much easier. I'll show two simple demos, one that passes messages between the two picos, and another that will control the LEDs on both Picos, using a JSON payload.
