Holybro Pixhawk 4 & PM07 14S Power Module Set

The Holybro Pixhawk 4 is fully compatible with the open-source ArduPilot and PX4 autopilot firmware ecosystems. It comes pre-flashed with a stable version, and you can update it via Mission Planner or QGroundControl. The NuttX RTOS provides a reliable real-time environment for executing complex autonomous flight algorithms.

The included PM07 Power Module supports a wide input voltage range from 2S to 14S LiPo batteries, which translates to approximately 6V to 50.4V. It provides accurate voltage and current telemetry back to the flight controller, with a maximum current sensing capability of 120 amps, making it suitable for large multirotors and fixed-wing aircraft.

The Pixhawk 4 incorporates a specifically designed vibration isolation system that mechanically decouples the sensitive IMU sensors from high-frequency motor and propeller vibrations. This results in cleaner accelerometer and gyroscope data, which allows the flight control filters to operate more effectively, leading to smoother, more stable flight, especially in aggressive maneuvers or on high-power platforms.

The controller offers extensive I/O for expansion, including two dedicated external SPI buses (with six chip select lines) for high-speed sensors, four I2C buses (two for general use, two grouped with serial ports for GPS/compass), multiple UARTs for telemetry, GPS, and serial peripherals, a CAN bus for additional modules, and standard RC input (SBUS/PPM). This allows for seamless integration of RTK GPS, optical flow, lidar, and companion computers.
