I'm making a model rocket and plan to include with it an altimeter and GPS system to find it in case I lose it. Currently, the components I have going in the rocket are a RFM9x and GY-GPS6MV2 connected to, call it, Nano B (Arduino nano). Connected to nano A (second nano, also going in the rocket), I…
