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.

After the onset of the KK2 series of boards, I have only used these boards for fixed winged aircraft to stabilize them in wind, correcting unwanted movement and they do quite well in that capacity.

Ron is it worth picking up one or two while that are on sale??? (Thanks for the video)

Oh my! Yes it is. Glad you pointed that out. I'm going to order a few because my daughter will soon be in Phisics and this would be a great an fun project for her. I don't believe I would know as much about control boards if I had not started on one of these. Thanks again for tipping me off.

Eric if you go to the listing above. Then click onto pic Two. That will show all you need. In that pic you will see the power pins and Motor control (together) on the Bottom Right Hand Side.

I have been on my laptop for three days trying to find the program to flash it and now i have a lot of things down loaded on it and still didn't get it flashed now im down longer and im changing the flight board to something else worst thing i have ever bought

Hi Joseph, In the [Files] tab, the third file down should be "flashing you multirotor control board". I wrote this some time ago so you can actually go to step 9 and start. Download the latest flash tool (if you are using Win7 or later you need to force it to allow you to upload unsigned programs), and open it up. You will also need to get a USBasp device and get the drivers for it as well. Once you have those two things, you will be able to flash your board to any configuration available for it. Lately all I use these for is to stabilize fixed winged aircraft by flashing them with Open Aero. You can also flash ESCs with SimonK firmware. Hope this helps and Happy flying!

Here is a quad I flashed with Xcopter using the V1 control board.

Well I am trying to set mine up. What should all 3 pots be set at for basic setup.
 RonRC 4297 points
NTHK, it depends on the diameter of your multirotor (motor to motor) prop diameter, and weight. I generally start with mine at about 40% bring it up, and if it oscillates quickly, back down just until it stops. if it doesn't oscillate, increase the gains until it starts then back down til it stops. Hope this helps and Happy flying!

: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.
