HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA)

HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA)
HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA)

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.

Size: 50.5mm x 50.5mm x 23.5mm
Weight: 14.5 gram
IC: Atmega328 PA
Gyro: Murata Piezo
Input Voltage: 3.3-5.5V
Signal from Receiver: 1520us (4 channels)
Signal to ESC: 1520us

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).

Note: A user manual is available under the files tab.
*Royalties paid on each unit sold to Rolf, the original KK Designer.

Josh it comes flashed for a Plus Copter (Cross config). You can flash it to a X or many other configurations.

I have this control card, and my Y-scorpion uses 6 servos, where 3 are facing down and the other 3 facing up. In what order do i need to connect the ESC to the board? I was thinking: M1: Left up M2: Right Up M3: Back Up M4: Left Down M5: Right Down M6: Back Down Would this be good or do i need some other order?

I received mine. It is same like version 2.1. Only Difference is Bigger flash memory.

So far I don't found any KK firmware which demand Atmega328 PA. So Older Board is still useable and performing same.

The best KK Board with lots of memory storage for future R&D codes enhancements.

3 Stars for quality of construction. Some of the solder joints are untidy (but seem electrically sound). More worrying was the large amount of solder flux left over on the bottom side. Little bit of canned flux remover did the trick but it's something to be wary of.

The vulnerability of the yaw gyro to damage worries me slightly. Time will tell wether it stands up to use or gets knocked around.
