A tiny, richly-featured Air Data Computer (ADC) for small unmanned airplanes. Includes an MS5611 barometric pressure sensor for 10cm-resolution altitude, a Honeywell RSC-series differential pressure transducer for extremely accurate airspeed, and a thermistor interface with high-resolution convertor for air temperature measurement with less than 1 degree precision. All of this interfaces to your autopilot via robust UAVCAN interface - no sketchy I2C wiring! Comes fully assembled, ready to use!
Existing solutions for airspeed measurement on Pixhawks are lacking - they're only a simple pressure transducer, usually with poorly-chosen range, giving airspeed at unacceptable resolution. They usually connect via I2C, which is a board-level interface - it should never be used for long-distance communications. Further, the barometers in most autopilots are simply mounted to the board with no way to plumb a static pressure source, so you're measuring the pressure of the inside of your fuselage, not true static pressure!
