Holybro Pixhawk 4 & PM02 12S Power Module Set - Aluminum Case

The Holybro Pixhawk 4 is fully compatible with both the PX4 and ArduPilot open-source autopilot firmware stacks. It comes pre-loaded with a stable version of PX4, but you can easily flash ArduPilot using Mission Planner or QGroundControl. The extensive processor resources and I/O make it suitable for complex custom applications within these ecosystems.

The included PM02 V3 power module supports a wide input voltage range from 2S to 12S LiPo batteries, which is approximately 6V to 50V. It provides regulated 5.5V power to the flight controller and peripherals and features a high-precision current sensor capable of measuring up to 120A for accurate battery telemetry.

The Pixhawk 4 incorporates a newly designed vibration isolation system using soft mounting for its primary IMUs. This mechanical filtering attenuates high-frequency vibrations from motors and propellers before they reach the accelerometers and gyroscopes. The result is cleaner sensor data, which leads to more accurate state estimation, smoother PID controller response, and overall better flight stability, especially on larger or powerful multirotors.

The board offers extensive connectivity for system expansion. It provides two external SPI buses (with six chip select lines) for high-speed sensors like optical flow or additional IMUs. There are four I2C buses, two of which are dedicated for external peripherals, and two are grouped with serial ports for connecting GPS/compass modules. Multiple UARTs, a CAN bus, and numerous PWM/S.Bus outputs are also available.
