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.

Will this control board board bind with my flysky fs-6t transmitter or do I have to use a reciever anyway such as the one from my flysky? Kindest regards Slade

You need to have a separate receiver. Any brand will do, as long as it has at least 4 channels.

Does it have auto leveling function?
 Doobieman 137 points
Yes. It will automatically attempt to stabilize your craft.

aED, No it doesn't have autoleveling. It only has gyros to helps maintain it's position what ever position that may be. Once tuned up, it can fly very nicely but it will not level itself after letting go of the sticks. My version 1 board flew quite nicely but it does take tuning. Hope this helps and Happy flying!

Thanks RonRC. Can you suggest a FC that I can use with auto leveling for my mini quad FPV build?
 RonRC 3229 points
aED, I would recommend getting the KK2.1.5. It's easy to setup and fly. All the best and Happy flying!

thanks Daniel that did the trick!

Hey Aaron, you need to switch the wires up that connect to your motors. Take the two wires that aren't the ground, and switch their positions around. This is how you change the spinning direction of the motors. Remember, you need two spinning CW and the other two spinning CCW

:Hello from India:
This comes with an Atmega 328 so more memory (although almost all firmwares can be installed in 168).I made successful quad for my project using the v2.1 .now making one currently using this one .If anyone from india needs help mail me at

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.
