Product Details

Pixhawk 4 is the latest update to the successful family of Pixhawk flight controllers. It is designed and developed in collaboration with Holybro and the PX4 team, optimized to run the full Dronecode stack and comes preinstalled with the latest PX4 firmware (v1.7).

The Pixhawk 4 features a new smaller form factor, more computing power, and 2X the RAM than previous versions. Additionally, it is equipped with new sensors with higher temperature stability, integrated vibrations isolation, increased ease-of-use: pre-installed with most recent PX4 (v1.7), and extra ports for better integration and expansion.

It contains the most advanced processor technology from ST Microelectronics, sensor technology from Bosch, InvenSense and a NuttX real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.

The Pixwhawk 4’s microcontroller now has a 2 MB flash memory and 512KB RAM. With the increased power and RAM resources, developers can be more productive and efficient with their development work. More complex algorithms and models can be implemented on the autopilot.

High-performance, low-noise IMUs on board are designed for stabilization applications. Data-ready signals from all sensors are routed to separate interrupt and timer capture pins on the autopilot, permitting precise time-stamping of sensor data. Newly designed vibration isolations enable more accurate readings, allowing vehicles to reach better overall flight performances.

The two external SPI buses and six associated chip select lines allow adding additional sensors and SPI-interfaced payload. There are a total of four I2C buses, two dedicated for external use and two grouped with serial ports for GPS/Compass modules.

The Pixhawk 4 autopilot development kit is perfect for developers at corporate research labs, startups, and for academics (research, professors, students).
