For autonomous and advanced UAV projects
The PIX6 is made for projects needing plenty of ports, high reliability and advanced autonomous functions, particularly larger multirotors, VTOL, airplanes, ground vehicles and robots. Thanks to ArduPilot support it handles Waypoints, return-to-home, GeoFence and RTK positioning.
Compatible with ArduPilot and Mission Planner
The RadioLink PIX6 is compatible with ArduPilot and works with Radiolink Mission Planner, ArduPilot Mission Planner and QGroundControl for firmware, parameters and advanced configuration. Source code and hardware definition are available via ArduPilot:

Software and mechanical vibration damping
The PIX6 combines software-based and mechanical vibration damping to filter out high-frequency vibrations for steadier sensors, better altitude hold and more accurate positioning. This is particularly valuable in larger multirotors and helicopters where motor and propeller vibrations would otherwise affect the readings.
Dual Gyros for greater safety
The PIX6 has dual Gyros and accelerometers, BMI088 and ICM-42688. If the primary Gyro reports deviating values, the system can switch to the secondary one for extra safety.
16 output channels for flexible builds
With 16 output channels (8 main and 8 auxiliary), the PIX6 is highly flexible and suits everything from simpler multirotors to hexacopters, octocopters, Y6, X8, VTOL, helicopters and custom-built systems.
- Dual-copter, tri-copter and quadcopter
- Hexacopter, octocopter, Y6 and X8
- Helicopters, airplanes and VTOL
- Cars, boats and submarines
- Robots, radar trackers and lawn mowers
- Agricultural vehicles and other autonomous ground systems
Integrated OSD for clear flight information
The integrated OSD module shows key flight information directly in the video image with no external module – a good overview during FPV and autonomous missions. It can display flight mode, distance, GPS status, longitude and latitude, vertical speed, battery voltage, current, wind speed, return path, route, vibration status and heading, depending on firmware and equipment.
Support for secondary development
Because the PIX6 is based on the ArduPilot ecosystem, functions can be adapted to specific requirements, making it attractive for education, research, prototypes and custom solutions.
Dual GPS units and RTK support
The PIX6 supports dual GPS units for better redundancy and higher precision and, with RTK equipment, can be used where high positioning accuracy is needed, such as mapping, autonomous missions, agricultural vehicles and inspection.
Waypoints, automatic return and GeoFence
The PIX6 supports Waypoints for automated driving and flying; depending on model type, hundreds can be stored for longer missions. When correctly configured it also supports automatic return via switch, on signal loss and on low battery voltage, plus GeoFence. Always check local regulations, flight zones and safety requirements before using autonomous functions.
Guide for setting up Waypoints:
HD digital and analog video transmission
The PIX6 supports analog video plug-and-play, and HD digital video such as the DJI Digital FPV System, DJI O3 Air Unit and Caddx Walksnail Avatar HD System can be connected via the DiViT adapter board.
Included power module with a wide voltage range
The included power module supports 2–12S batteries, measures voltage and current and provides a stable BEC output to the PIX6.
- Input voltage: 2–12S, 7.4–50.4 V
- Maximum detection current: 90 A
- BEC output: 5.3 V ±0.2 V
- BEC output current: 2 A
Automated quality testing
The PIX6 is tested with an automated software testing system covering sensors, ports and interfaces, giving consistent quality and higher reliability than manual testing alone.
A cost-effective solution for larger systems
The PIX6 can be combined with Radiolink’s RTK positioning system, GPS solutions and ground systems into complete solutions for drones, agricultural vehicles and autonomous ground vehicles, and is especially suited to advanced systems with high precision and automated missions.
Suitable for many applications
- Larger multirotors
- VTOL and airplanes
- Helicopters
- FPV and long-range platforms
- Mapping and surveying
- Inspection and autonomous search
- Agricultural vehicles and smart farming
- Robots and autonomous ground vehicles
- Boats, submarines and custom-built systems
- Education, research and development projects
PIXHAWK or PIX6 – which one should I choose?
The RadioLink PIXHAWK suits anyone who wants a classic, proven Pixhawk-based Flight Controller with stable ArduPilot use. The PIX6 is the more modern model for advanced systems where 16 output channels, dual Gyros, an integrated OSD, dual GPS units and RTK support matter.
- Choose the PIXHAWK if you want a proven ArduPilot/Pixhawk platform for broad RC and UAV projects.
- Choose the PIXHAWK if you are building a system where classic Pixhawk compatibility and stable operation matter most.
- Choose the PIX6 if you need more output channels, dual Gyros, an integrated OSD and more advanced functions.
- Choose the PIX6 if RTK, dual GPS units and larger autonomous systems are a central part of the project.
