Stratux & OpenVario with AHRS, ADS-B and Flarm I/O

The low-cost open-source anti-collision system for private aviation and gliders.

Assemble and modify your Stratux or OpenVario flight computer right.

Upgrade your current Stratux with AHRS or barometric pressure sensor, even when you use a case which does not officially support this, due to space reasons.

Feature of upgraded Stratux or OpenVario flight computer:

  • 1090MHz ADS-B ES (IN)
  • Mode S/C (IN)
  • Flarm, (I/O)
  • Open Glider Network (OGN), (I/O)
  • OGN Drones, (I/O)
  • PilotAware (PAW), (I/O)
  • Flying ad-hoc Networks (FANET), (I/O)

I/O = receives and sends; IN = receives only.

You already use a Stratux? Upgrade it with additional Sensors!

  • Our developed and optimized circuit boards (PCB) enable proper connection to any additional sensor e.g. GY-91 – MPU9250/ MPU9255 for AHRS functionality, or GY-BMP280 for barometric pressure (altitude), since the official Stratux AHRS module is no longer available.
  • Add Flarm in/ out to become visible for gliders and be able to see them on your tablet, to aviod collision. Available for both, Stratux and OpenVario.


Stratux and OpenVario are not an approved or certified aid for flight execution.
