Description

Used to implement a break for RC-planes. It basically PWMs a breaking solenoid in each landing gear.

 

PCB

 

It has hardware for:

  • 3 outputs at 10A each.
  • inputs for 3 wheel speed sensors.
  • accelerometer to aid in ABS braking
  • EEPROM 128kb to stora settings and datapoints.
  • USB micro plug (easily config via usb serial)
