Overview

  • Building a flight computer no larger than 100mm x 30mm
  • Using two IMU's... for sqrt(2) noise reduction
  • embedded PCB antenna for LoRa RF; Trying to get some cost savings
  • Two CAN Bus Lines; but doing it on the Cheap so im basing it with the STM32G0B1RET6
  • USB and SD Card; so i can do mass trasfer of data files using the USB Port
