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
