Overview
About Radiolink Pixhawk Flight Controller (UAV).
The Radiolink Pixhawk is a 32-bit Pixhawk-class autopilot aimed at UAV, fixed-wing, multirotor and rover builders who want a complete, ready-to-fly ArduPilot/PX4 platform. It is based on the proven STM32F427 Cortex-M4 main processor at 168 MHz with a separate STM32F100 failsafe co-processor, delivering the same open-source flight-stack capability as the original Pixhawk reference design.
Its sensor package combines an L3GD20H gyroscope, LSM303D accelerometer/magnetometer, an MPU6000 IMU and an MS5611 barometer, which the firmware fuses for stable attitude, heading and altitude estimation. The board provides extensive I/O - multiple UARTs, CAN, I2C, SPI, SBUS/PPM input and 14 PWM outputs (8 main plus 6 aux) - and supports a MicroSD card for logging, a safety switch, buzzer and power module.
Radiolink bundles its Pixhawk with accessories that vary by package, often including a Radiolink M8N-class GPS, telemetry support and power module, which makes it a convenient turnkey choice for educational drones, survey and mapping platforms and autonomous research vehicles. It is configured with Mission Planner or QGroundControl for full mission planning, autotune and live telemetry.

Buying guide
How to choose.
The Radiolink Pixhawk is a good pick when you want a complete, branded Pixhawk-class kit rather than sourcing every accessory separately. Packages frequently bundle a Radiolink M8N GPS, power module, buzzer, safety switch and SD card, so confirm exactly what is in the box for the listing you choose.
Like other FMUv2/F4-generation autopilots it uses an STM32F427 with 2 MB flash, which is excellent for mainstream ArduPilot/PX4 missions but has less headroom than newer H7 boards. For survey, mapping, fixed-wing and rover work where the standard feature set is sufficient, it is a reliable, cost-effective platform.
For Indian buyers it is a practical turnkey autopilot for educational and commercial-style UAV builds. If you need redundant temperature-controlled IMUs, more processing power or the latest firmware features, step up to a Pixhawk 6C; choose the Radiolink when value and a complete out-of-box kit matter most.
FAQ
Common questions.
What firmware does the Radiolink Pixhawk run?
It runs the open-source ArduPilot and PX4 flight stacks, the same as standard Pixhawk autopilots. You configure it using free ground-station software such as Mission Planner or QGroundControl, choosing copter, plane, VTOL or rover firmware to match your vehicle.
What is usually included in the kit?
Contents vary by package, but Radiolink Pixhawk bundles commonly include the flight controller, an M8N-class GPS, a power module, buzzer, safety switch, SD card and connecting cables. Always check the specific listing, since some versions ship the board with fewer accessories.
How is it different from a generic Pixhawk 2.4.8?
It shares the same STM32F427 processor and Pixhawk architecture, but Radiolink produces it as a branded product with its own quality control, casing and accessory ecosystem. Functionally both run ArduPilot/PX4; the Radiolink version is sold as a more complete, supported kit.
How many motor and servo outputs does it have?
The board offers 14 PWM outputs - 8 main outputs plus 6 auxiliary - which is enough for multirotors up to octocopters as well as fixed-wing aircraft with multiple control surfaces, gimbals, retracts and other servo-driven accessories.
Is it suitable for fixed-wing and VTOL aircraft?
Yes. Because it runs ArduPilot and PX4, it supports fixed-wing planes, VTOL hybrids, multirotors and ground rovers. You select the matching firmware and configure the airframe, control surfaces and motor mapping in the ground-station software.
Does it support a GPS and compass for autonomous flight?
Yes. It connects to a U-blox M8N-class GPS with integrated compass via its dedicated GPS UART and I2C ports, enabling position hold, waypoint missions and return-to-home. Many Radiolink kits include a compatible GPS module in the box.
