It had a good run, but the Nav Board M3 is now EOL. Please consider X-Monkey as a more capable replacement for navigation use.


Lady GaGa flight support

November 10, 2013

demoWe are happy to have provided flight control and power train / electrical support to Lady GaGa's Volantis project. Check out the blog for more information!


Our GUI software is free!

Software highlights include:

Are options available?

  • Artificial horizon and heading visual indicators
  • Sensor data graphs
  • Easy calibration of accelerometer and magnetometers
  • Input of local magnetic declination data (for true north output from CHIMU)
  • Special functions for CHIMU including DAC offsets and serial port output rate changes
  • GPS status and lock information (Monkey only)
  • PWM output and analog input status (Monkey only)
  • Data logging
  • CHIMU configuration logging

Please Note:

Some platforms have a hard time displaying all the data from CHIMU at full speed. You will get false checksum errors as a result, but the issue is in display handling and serial port handling on older machines. If this is the case, turn the CHIMU serial port rate down (10 Hz for example) and / or turn off some of the messages to lower the thruput requirement on your PC.
