The Balloons Gen 1 Avionics Platform is the first core avionics suite developed by HABEES. Named Oscar, this avionics suite flew on a failed technology demonstration in SSI-39, followed by a successful demonstration in SSI-40. As the first core avionics suite, it set the expectations for features to be included in subsequent revisions.

The full list of features found on Oscar:

  • Teensy 3.2 Main MCU
  • Five total pressure/temperature sensors, including two BMP280's, two MS5803's, and one MPL3115A2
  • Micro SD card data logging
  • Real Time Clock with backup battery
  • Thermocouple for external temperature sensing
  • uBlox NEO-6M GPS
  • 6 custom-use MOSFET's
  • Current sensing on two MOSFET's
  • Indicator LED's for flight critical states
  • Battery Protection (OV/UV/OC)
  • 5V Battery Boost
  • RockBlock Satellite Communications
  • Pinouts for I2C, SPI, Power
