HobbyKing Multi-Rotor Control Board V2.1 (Atmega168PA)

HobbyKing Multi-Rotor Control Board V2.1 (Atmega168PA)
HobbyKing Multi-Rotor Control Board V2.1 (Atmega168PA)

Based on and built in conjunction with the original QUADBoard designer Rolf and the popular and already well supported KK Control board, the Hobbyking Multi-Rotor control board is bringing Quadcopter 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 Atmega168PA IC.

Specs.
Size: 50.5mm x 50.5mm x 23.5mm
Weight: 14.5 gram
IC: Atmega168PA
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 4 rotor Aircraft (Quadcopters). 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 Atmega168PA IC. The Atmega168PA 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 Quadcopter.

The HobbyKing Multi-Rotor control board also uses signals from your radio systems receiver (Rx) and passes these signals to the Atmega168PA 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 to Rolf, the original KK Board Designer.

hi, when connected there is no beeps of esc of flashining of the led. theres just the led lit up constantly. the esc and motors works fine since I tested them with the rx module attached. cant understand whats wrong. thank you in advance.

Are you arming it properly? You need to hold the throttle/rudder stick down and to the left to arm it, you may need to adjust the trims or reverse a channel to make that happen properly.
 arun 1 points
I think yes, have tried every possible position of the rudder/throttle stick in case if the channel is reversed. The board and the transmitter are straight out of the box, do they need any programming/flashing before they work?
 RonRC 3700 points
arun, you may want to check to see if all your servo leads from the ESCs are plugged in properly. Signal always inside and ground outside. If they are, you may want to trim your throttle down until it arms with the throttle stick down and to the right on yaw. Try to the left as well and if it works to the left, then you need to reverse your Yaw channel. This board will do a great job of stabilizing a multirotor if you take the time to tune it properly. Hope this helps and Happy flying!

What firmware should I program with? have tested all and noting happens. have armed the ESC so they are good
 MayhemNKMC 319 points
Are you arming it properly? You need to hold the left stick down and to the left to arm it, you may need to adjust the trims or reverse a channel to make that happen properly. If you have tried all that, I would start over from the beginning. There is a great write up from RCExplorer on the set up and calibration of these boards. It also has the instructions for flashing them as well. The firmware depends on the Multirotor you are building but Kaptain Kuk Or Min Soo should work just fine.

Hi, Is it possible to use the controller as a stabilizer for Gimbal ? Regards Eitan
 MayhemNKMC 319 points
thats not what it is designed for, but It is posible. You would have to figure it out. I would use it with the XXcontrol_KR_AeroPlane v2.9
firmware. You should be able to plug roll into aileron, Pitch to the elevator and yaw to the rudder. But it will not work for a brushless gimibal.
 eitan 8 points
Thanks for the answer I figure it to XXcontrol_KR_AeroPlane v2.9 How the Control Board arming?
 MayhemNKMC 319 points
You would have to either try usings a splitter to throttle and rudder to arm it and remove them once armed. Or you could put them to spare channels on the radio. My plan was to build a controlable gimbal that would be seperate from the aircraft with a dedicated radio for a "camera" pilot, so I didn't consider arming it remotely.
 eitan 8 points
I'm sorry, I do not understand how to connect the splitter
 MayhemNKMC 319 points
I mean a Y-splitter. Like you would use to connect aileron servos.
 eitan 8 points
Do you mean in other words, to make a short between throttle and rudder on the receiver's inputs to arming, then disconnect the connection? If so, the controller does not arming.
 MayhemNKMC 319 points
No, do not short the board. I mean making a connection to the radios RX on the throttle and the rudder. Like I said, its going to take some tinkering to make it work.
 eitan 8 points
Hi, First of all I want to thank you for your help and patience. I can not connect it to the RX, The Gimbal was designed for another purpose, it is supposed to work independently. On second thought, there is no self leveling option in the Control Board V2.1 , So it is not suitable for Gimbal.
 MayhemNKMC 319 points
Too true, it will not work independently. Since I am upgrading to the KK2.1.5 board and I have extras of these, I plan to use them to stabilize an independently controlled gimbal, "flown" by a second pilot.
 MayhemNKMC 319 points
Just tested it as I intended to use it and that will not work either, I think the only way this could be used would be on something like the SSG gimbal. All this does is counter movement, I was thinking it would work like a heading lock gyro. It will not work that way.

Hi to all! does anyone knows if this board is able to have a self leveling mode like the kk2 board? Tank you in advance.
 MayhemNKMC 319 points
Unfortunately, No, these do not have auto-level. I have been flying my tri-copter with one of these but I am stepping up to the LCD KK2.1.5 for the autolevel for my bigger multirotors.

Better Board than version 1 for almost the same price. I damaged V1 in a crash and then bought this one..

With V2 you can fly Hexacopter. Very easy to use and program with appropriate usb flash tool (from eBay)

If board had smd gyros instead of Piezo (for less drift) it would be a winner.

Una pasada venia dentro de una cajita de goma espuma negra de esa prensada, la he usado para poner la tapa debajo de la placa para evitar las vibraciones y luego tapare todo el conjunto con el resto, en poder pongo fotos. La placa esta ok con ese enbalaje no le puede pasar nada un 10 para hobbyking. Los pines del motor M5 y M6 no están soldados, acordaros de soldarlos po si algún día hace falta y os toca desmontar todo. Saludos.

The board works very well. Flashed it with the AVR programmer I obtained off ebay and worked like a charm. Maybe one of the downsides is the bottom of the board where the solder mounds are is slightly dirty. I'm not sure if this is from the flux that was used to solder the board or if its just poor quality control. Either way it is purely cosmetic and does not affect the functions of the board. Also keep in mind that when you are taking the board out of the foam box it arrives in, be sure to pull it straight out - as pulling it out at an angle will cause the vertical yaw gyro to bend. Had this happen to me, but I realized what was happening and bent it right back into place.

This board is a great deal for those starting out in multicopters. I think it's awesome that HK has these at such a low price. Other vendors charge $10 each just for the gyros. I couldn't stop laughing when the other vendors boards went from $80 to $40 once HK started selling these, and theirs are still one and a half times the price!!!. Now if HK would make one with mems gyros and camera compensation at a crazy low price they would dominate the multicopter comunity!!!.
