This is the Nora + autopilot from CUAV. It has internal vibration dampening and high end PCB layout and maximum component integration. Higher end IMU. Less sensor drift. Better dead reckoning performance than less expensive boards. You definitely get what you pay for.
Nora® is an advanced autopilot independently designed by CUAV®. It uses a higher-performance STM32H7 processor and integrates industrial-grade sensors and ultra-low temperature drift sensors. Compared with the previous flight controller, it has better performance and more reliability. This board can run ArduPilot firmware perfectly. Nora is ideal for academic research and commercial systems integration.
