CUAV Nora Overview

../_images/nora.png

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

Other characteristics

  • Internal shock absorption
  • Ports on the sides
  • Supports High Speed USB (480mb/s), can download logs faster
  • Supports more DShot outputs
  • Supports IMU temperature control, making the sensor more consistent
  • Dedicated UAVCAN battery port
  • 3 sets of IMU sensors

Default UART Order

  • SERIAL0 = console = USB
  • SERIAL1 = Telemetry1 = USART1
  • SERIAL2 = Telemetry2 = USART6
  • SERIAL3 = GPS1 = USART1
  • SERIAL4 = GPS2 = UART4
  • SERIAL5 = USER = UART8
  • SERIAL6 = USER = UART7 (DEBUG TX/RX)

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 UAVCAN power module and battery monitor, CAN PMU Power detection module . Connect to one of the CAN ports and its already pre-configured for use.
