Based on the popular and already well supported KK Control board, the Hobbyking Multi-Rotor control board is bringing Multi-Rotor madness to the masses with its breakthroughs in quality and price!

The HobbyKing Multi-Rotor control board uses Japanese Murata piezo gyros that are less sensitive to vibration than SMD type gyros and also features state of the art SMT manufacturing to ensure quality. This board also uses a user programmable Atmega328PA IC.

Whats is a Multi-Rotor Control board you ask?

The HobbyKing Multi-Rotor controller is a flight control board for multi-rotor Aircraft (Tricopters, Quadcopters, Hexcopters). Its purpose is to stabilise the aircraft during flight. To do this it takes the signal from the three on board gyros (roll, pitch and yaw) then passes the signal to the Atmega328PA IC. The Atmega328PA IC unit then processes these signals according the users installed software and passes control signals to the installed Electronic Speed Controllers (ESCs). These signals instruct the ESCs to make fine adjustments to the motors rotational speed which in turn stabilises your multi-rotor craft.

The HobbyKing Multi-Rotor control board also uses signals from your radio systems receiver (Rx) and passes these signals to the Atmega328PA IC via the ail, ele, thr and rud inputs. Once this information has been processed the IC will send varying signals to the ESCs which in turn adjust the rotational speed of each motor to induce controlled flight (up, down, backwards, forwards, left, right, yaw).
