High-Altitude Balloon Controller

This will be the second balloon controller I make[^1]. Features:

  • RP2040-based controller (Pi Zero, probably).
  • RFD900 radio link (probably limited to 64 kbps).
  • APRS backup link.
  • Pressure sensor.
  • Internal and external temperature sensors, as well as sensors on the GoPros.
  • HA GPS.
  • Camera for downlink (hopefully we can get some low-res images).
  • MAVLINK protocol (not sure if I can find a way to send images).
  • GoPro cameras, one up, one out.

[^1]: The first was based on an old Make Controller board and a custom PCB with Microhard radio, pressure sensor, thermistors, and GPS. It also had a backup APRS transmitter and two GoPro cameras.
