FAQ & Known Issues

  • No support for integrated HopeRF RFM22B 100mW 433MHz radio.


In the Hardware Configuration tab you can enable the Accelerometer, Barometer and Magnetometer under System Configuration.

CPPM receiver

  • Attach the receiver CPPM output to pin 5 of the Flex-IO header.
  • Enable RX_PPM

Battery voltage monitoring

Assuming you have physically connected a voltage divider (Basic voltage sensor) as per the instructions on the LibrePilot wiki.

  • Enable VBAT
  • Battery Voltage Scale should be set to 55. Note: this value will vary depending on resistor tolerances etc...

This configuration is suitable for 3/4S
