Proven platform for ArduPilot projects
The RadioLink PIXHAWK is built on a well-established Flight Controller platform suitable for advanced hobby projects, education, research and custom-built UAV systems, from multirotors and airplanes to boats, cars, submarines and robots, and parameters can be set via Radiolink Mission Planner, ArduPilot Mission Planner and QGroundControl.
Redesigned circuit construction
RadioLink has reworked the circuit design to reduce interference from internal components and deliver cleaner signals, aimed at more accurate compass data, more stable altitude hold and more stable operation when the system is correctly installed and calibrated.
Automated quality testing
Every RadioLink PIXHAWK is tested with an automated software testing system covering sensors, connection ports and interfaces, which gives consistent quality and reduces the risk of faults – especially valuable for a Flight Controller with many functions and connections.
Stable production and component handling
RadioLink uses antistatic and automated SMT production to reduce interference and variation between units, and components such as the processor and sensors are managed through established supply chains in a controlled production environment for better durability and reliability.
Support for obstacle avoidance with SUI04
The RadioLink PIXHAWK can be used with an external I2C expansion board and up to 6 SUI04 ultrasonic modules for forward, backward, left, right and upward obstacle avoidance as well as downward altitude hold, depending on the installation, configuration and chosen peripherals.
Included power module with a wide voltage range
The included power module supports 2–12S batteries and a wide voltage range of 7.4–50.4 V, can measure both voltage and current and delivers a stable BEC output to the Flight Controller.
- Input voltage: 2–12S, 7.4–50.4 V
- Maximum detection current: 90 A
- Maximum detection current per ESC: 22.5 A
- BEC output: 5.3 V ±0.2 V
- BEC output current: 2 A
Support for several model types
The RadioLink PIXHAWK can be used in many different types of projects and suits airborne, ground-based and water-based systems alike, where ArduPilot support and broad configuration options are important.
- Airplanes and flying wings
- Multirotors with 2–8 motors
- Helicopters and VTOL
- Cars and robots
- Boats and submarines
- Radar trackers and custom-built systems
- Lawn mowers and autonomous ground vehicles
- Education, test platforms and development projects
Support for further development and firmware
The RadioLink PIXHAWK supports further development and parameter encryption and can be configured via Radiolink Mission Planner, ArduPilot Mission Planner and QGroundControl; the latest firmware and instructions should be downloaded from Radiolink’s official support and download pages, and functions may vary depending on the firmware version and chosen model type.
DShot and flexible outputs
The RadioLink PIXHAWK has 8 configurable OneShot/PWM outputs and 6 configurable AUX outputs, and the DShot protocol is supported when upgrading to firmware V4.0 or later, making the system flexible for several types of ESC and servo installations.
PIXHAWK or PIX6 – which one should I choose?
The RadioLink PIXHAWK is a good choice for anyone who wants a classic and proven Pixhawk-based Flight Controller with broad model compatibility and stable ArduPilot use, while the RadioLink PIX6 is the more modern and feature-rich model for advanced systems where 16 output channels, dual gyros, integrated OSD, dual GPS units and RTK support are important.
- Choose the PIXHAWK if you want a proven ArduPilot/Pixhawk platform for wide-ranging 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, 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.
