Breakout Board Flight Computer
A super simple flight computer that entails only breakout boards mounted directly to the av bay.
Example parts:
Microcontroller - https://www.digikey.com/en/products/detail/stmicroelectronics/NUCLEO-G431RB/10231584 (or a Teensy 4 for $5 more, but staying in the STM32 family makes it easier to port SPICA code)
IMU - https://www.adafruit.com/product/4634
Altimeter - https://www.adafruit.com/product/1893
GPS - https://www.adafruit.com/product/746
XBee (this would need a custom breakout board PCB, or use a different transmitter) - https://www.digikey.com/en/products/detail/digi/XBP9X-DMRS-001/5972743
The above would cost $185 total, with $106 of that being the XBee which could be swapped with a much cheaper transmitter.
If we need deployments those could be handled by relays on separate batteries.
We also may want some kind of nonvolatile storage.
Just an idea if we don't have the resources to make custom PCBs. The above could also go on a perf board.
