CUAV Nora Overview


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 previous autopilots, it has better performance and more reliability. Nora is ideal for academic research and commercial systems integration.

  • SERIAL2 = Telemetry2 = USART6 (TELEM2)


  • SERIAL4 = GPS2 = UART4 (UART4)




Serial protocols can be adjusted to personal preferences.

DShot Capability

All motor/servo outputs are DShot and PWM capable. However, mixing DShot and normal PWM operation for outputs is restricted into groups, ie. enabling DShot for an output in a group requires that ALL outputs in that group be configured and used as DShot, rather than PWM outputs. The output groups that must be the same (PWM rate or DShot, when configured as a normal servo/motor output) are: 1-4, 5-8,and 9-12. Outputs 13 and 14 are not DShot capable.

Battery Monitor

The autopilot includes a DroneCAN power module and battery monitor, CUAV CAN/DroneCAN Power Module. Connect to one of the CAN ports and it is already pre-configured for use.
