Grab'eM KK 5.5 MULTICOPTER CONTROLLER  (Black)

The KKmulticopter v5.5 board is a flight control board for remote control multicopters with 2,3,4 and 6 rotors. It’s purpose is to stabilize the aircraft during flight. To do this it takes the signal from the three gyros on the board (roll, pitch and yaw) and feeds the information into the Integrated Circuit (Atmega IC). This then processes the information according the KKmulticopter flash tool software and sends out a control signal to the Electronic Speed Controllers (ESC’s) which are plugged onto the board and also connected to the motors. Depending upon the signal from the IC the ESC’s will either speed up or slow down the motors (and tilt the rear rotor with a servo in a Tricopter) in order to establish level flight.
