Pixhawk 4 is the latest update flight controller, this autopilot features a small size, and 2X the RAM than previous versions. Additionally, it is equipped with new sensors with higher temperature stability, integrated vibrations isolation, and extra ports for better integration and expansion.
It contains the most advanced processor technology and a NuttX real-time operating system, providing incredible performance, flexibility, and reliability for controlling.
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. High-performance, low-noise IMUs on board are designed for stabilization applications. Newly designed vibration isolations enable more accurate readings, allowing drones to reach better overall flight performances.
