Description

The Pixhawk 4 represents a significant evolution in open-source flight control hardware, developed jointly by Holybro and the PX4 Autopilot team. Its core is the powerful STM32F765 microcontroller, which delivers over double the computational power and RAM of previous generations, enabling the execution of complex autonomous navigation algorithms and high-rate data logging directly to the onboard microSD card.

Engineered for robustness in demanding environments, the controller features a suite of high-stability sensors from Bosch and InvenSense, including the ICM-20689 and BMI055 IMUs. The dedicated vibration isolation system mechanically decouples these sensors from frame harmonics, ensuring clean data for precise attitude estimation and control, critical for heavy-lift and mapping platforms.

Key Features

  • Advanced Processing Core: STM32F765 Cortex-M7 FMU paired with an STM32F100 Cortex-M3 I/O processor for robust, real-time task management.
  • High-Fidelity Sensor Suite: Includes dual accelerometer/gyroscope units (ICM-20689, BMI055), an IST8310 magnetometer, and an MS5611 barometer for accurate state estimation.
  • Professional-Grade Connectivity: Offers abundant expansion ports including 3 dedicated I2C buses, 4 SPI buses, and multiple UARTs for peripherals like telemetry, RTK GPS, and payloads.
  • Enhanced System Safety: Features redundant 5V power inputs with automatic switching, an external safety button for motor arming, and a high-power piezo audio indicator for system status.
  • Optimized Form Factor: Compact 44 x 84 x 12 mm design with a protective plastic case and pre-installed damping foam for easy integration into various airframes.
  • Developer-Ready Platform: Pre-flashed with PX4 firmware and supported by a full Dronecode software stack, ideal for academic research, corporate R&D, and commercial UAV development.

Applications

  • Heavy-lift agricultural and cargo drones requiring robust, redundant flight control.
  • Aerial mapping and surveying platforms integrating RTK GPS and advanced camera gimbals.
  • Research and development platforms for testing new autonomous navigation algorithms.
  • Commercial inspection drones (e.g., infrastructure, solar farm) needing reliable long-duration flights.
  • Advanced fixed-wing VTOL (Vertical Take-Off and Landing) UAV prototypes.

Frequently Asked Questions

Does this Pixhawk 4 kit include a GPS module?

No, this specific listing is for the Pixhawk 4 Flight Controller unit only and does not include a GPS module. The package contains the flight controller, power board, cables, and accessories. A compatible GPS module, such as the Holybro M8N or M9N, must be purchased separately and connected via one of the available serial ports.

What is the input voltage range for the Pixhawk 4's power module?

The included PM07 Power Management Board is designed for 2-6S LiPo batteries (approximately 7V to 26V DC). It provides redundant, regulated 5V power to the flight controller and peripherals. Always ensure your power source is within this range to avoid damaging the electronics.

Can I use this flight controller with ArduPilot firmware instead of PX4?

Yes, the Holybro Pixhawk 4 is fully compatible with both the PX4 and ArduPilot open-source autopilot stacks. While it ships pre-installed with PX4, you can flash ArduPilot firmware using Mission Planner or similar ground station software via the built-in USB port.

How many PWM outputs are available for motors and servos?

The Pixhawk 4 provides up to 16 PWM outputs. Eight outputs are managed by the main FMU processor, and an additional eight are handled by the separate I/O processor. This allows for complex multirotor, fixed-wing, or VTOL configurations with auxiliary servos for gimbals or payload mechanisms.

Package Includes

  • 1 x Pixhawk 4 Flight Controller (in Plastic Case)
  • 1 x Pixhawk 4 PM07 Power Management Board
  • 1 x I2C Splitter Board
  • 1 x Set of Connecting Cables
  • 1 x USB Cable
  • 1 x Foam Vibration Damping Set
  • 1 x Pixhawk 4 Quick Start Guide
