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.

Hello! I'm building my first quad and try to get this V3 board to work. Using the "KK Quad V4.7 with Stick Centering" package there are 3 hexfiles, these files just differs by that in their name there is a "SSx" where x is either 3, 4 or 5. What's the difference between these files? /Bengt

hi does it work ockay with a tricopter??
 RonRC 3692 points
blaz, if you flash it with tricopter firmware, it should do even better than it did with my quad because a tricopter doesnt mix the motors for yaw. It use a servo to tilt a prop to achieve yaw. Therefore, all the 3 rotors are only dedicated to only keeping the tri stable. Here is how stable it can fly with a quad. Hope this helps and Happy flying!

How can I configure this for X-quad while the flashing tool for the board is not available in HK as of now?. My quadcopter does not fly very well even experimenting with gain adjustments so having a hard time. Any help is appreciated.

Cyberdos, There are other places you can find the USBasp and a 10pin to 6pin cable then from there you will be able to flash it for Xcopter or whatever you choose. Lately, I've only used these boards on airplanes to compensate for gusts of wind. Hope this helps and Happy flying!

Thanks RonRc, any particular site you recommend? I think for now it is scarce in my locality.
 RonRC 3692 points
You may want to look at echo bravo alpha yankee. They have several and some with a 6 pin adapter.
 Cyberdos 4 points
I've got them instantly just right now from a local find but with 10 pin connectors instead of 6, will have to try if this will work, now my challenge is how to connect this 10 pin to 6 pin bus if it is possible. Thanks.
 RonRC 3692 points
On the above described location, you can get the 10 - 6 adapter for a buck fifty. All the best and Happy flying!

can i activate the GYRO FUNCTION of the RADIO with this control board HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA) ?
 RonRC 3692 points
Sibucat, no, these gyros are manually adjusted via onboard potentiometers This makes for pretty quick adjustments anyway. 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.

Hi, greetings from Portugal, to all lovers of this hobby I need information on if this Board can control servos or only speed controllers, thanks

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.
