Wombat was an experimental flight computer with a powerful onboard microcontroller, integrated programmable-frequency radio and uBlox 6 GPS. We used it as a test bed for a number of new ideas.

Technical details:

  • STM32F405RGT6 microcontroller at 168MHz with 192KB RAM, 1MB flash, DSP, FPU
  • uBlox NEO-6Q GPS with LNA and filters
  • ADF7012 radio, programmable over the entire 70cm ISM band
  • SMPS power supply from a lipo battery
  • Onboard battery backup, cutdown controller, micro SD card, USB

All the gory details (schematic, board files, code and so on) are available on github:

The beautiful PCBs for wombat r1 were provided by Cambridge Circuit Company, thanks!
