1.1.2 USX52 Compute Flight Controller

Product Description

The USX52 Compute Flight Controller combines the mature Pixhawk 6X flight controller architecture with the D-Robotics X5 AI chip, integrating stable flight control with edge intelligence in an onboard flight control platform. Based on PX4/ArduPilot firmware, it achieves highly reliable flight management. With the X5 chip's BPU AI computing power of 10 TOPS, it can run various neural network algorithms locally in real-time, including image recognition, object detection, semantic segmentation, human detection, object counting, spatial perception, reinforcement learning, and more. The CPU general computing power reaches 21.6 DMIPS/MHz, which can run VIO visual odometry, LIO LiDAR odometry, SLAM mapping and localization, Navigation2 navigation, path planning, and other algorithms without relying on cloud computing, completing the perception, planning, and action loop independently. The module is compatible with RTK, UWB, optical flow, ADS-B and other peripherals, supporting multi-sensor data fusion and intelligent mission planning, balancing flight safety, positioning accuracy, and operational autonomy. Widely applicable to industrial inspection, research and development, autonomous operations, and other drone scenarios with dual demands for flight stability and edge intelligence.
