The ground station is an RP2040 Embassy firmware (Adafruit Feather RP2040, same board as pico_logger) that bridges USB CDC serial and UART to interface with an RFD 900x-US radio modem. Primary use case is receiving telemetry from the rocket during flight.
Data flow: Computer <-> USB CDC <-> RP2040 <-> UART (57600 8N1, TX=GP0, RX=GP1) <-> RFD 900x
