After I get this project done, I plan on experimenting with swapping thing out.

1. Meshtastic node, any node with UART should suffice

2. MCU (currently the Arduino Mega)

2a. other Arduinos

2b. other MCUs

2c. SBC (pi zero or similar)

3. The LoRa transciever on the pi pico

And probably eventually making a custom board that puts most/all of this onto one PCB.
