Product description
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 (v1.8).
It features the currently most advanced processor technology from STMicroelectronics
®
, sensor
technology from Bosch
®
,InvenSense
®
, and a NuttX real-time operating system, delivering
incredible performance, flexibility, and reliability for controlling any autonomous vehicle.
The Pixhawk 4’s microcontroller now has a 2MB 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 enables more
accurate readings, allowing vehicles to reach better overall flight performances.
The two external SPI buses and six associated chip select lines allow to add additional sensors and
SPI-interfaced payload. There are 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).
