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.

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.

And when to connect the Flight control Board to my Quadcopter, the inputs is analogic or numeric inputs for throttle, aileron ... Because, I have a PIC to pilot my PWM's and send the values of PWM I control my quadcopter ( and my PIC) with Labview.

Damien all I know is that on my Quad and Turnigy9XV2 Mode 1 I need to pull the "Left Stick", Down (Full Down Elevator) and to the Left (Full Left Rudder). So that ARM my FCB. (The LED go on and stays on). I hope this helps.

Hi, I ordered this Multi-Rotor Board Control V2.1, and I have a Microcontroler PIC to send the motor values. When I connect the Multi-Rotor Board control, and I increased the values of engines, nothings happens. What must type of data sent to the Multi-Rotor Board Control V2.1 to flight
 NewToHobbyKing 13321 points
Damien this board (Flight Controller Board ) needs to be armed every time it powers up. You will know when it is armed because, once ARMED, the led (on the board) come on and stays RED. Once ARMED all the FCB function will respond. So are you arming your FCB. Please.

It was a Statement. Add few extra bucks and you can get Multiwii board with way more features and way more beginner friendly board. V2.1 is not for beginners. You have to all ways to correct sticks to keep aircraft level.
 NewToHobbyKing 13321 points
Taavi if so it is not setup correctly. But the reason we say it is better for Beginners is because of the LCD setup. Far easier that buying a Flash Usb card and flashing the board just to run X quad. In fact it works about the same price once you buy the extra Usb flash card.

The V2.1 Board does not have ACC sensor, so it will not return to level after realising the sticks. Also the boarad calibrates it self everytime when the thorttle sitck leaves from zero.
 NewToHobbyKing 13321 points
Taavi is this a Question or a Statement ? This board is very good but it does not do everything. If you pull you Throttle to Zero when off the ground the Aircraft will crash to the ground!

I have purchased this board as a first Quad Flight Control Board. It is a good board from what I can see thus far. However, it does not seem to Self Level like the KK Board even though it is supposed to be based on the KK Board. I find the self calibration a bit tricky when the tx is Zero Throttle as if the ground is not level at zero throttle then I get all sorts of trim issues. I have also found the Manual not very informative. I think it could have had a little more love. I think I will invest in the KK Board and see how much better it is overall.
 NewToHobbyKing 13321 points
Chris it is so much different ti the KK 2.0 or 2.1. This board is very basic and if I had to do it all over again I would go for the KK series. That said once you have this board setup and working, it can be a lot of fun.

Chris, this board has no self level function, only gyros to hold what ever position you put it in. This board does not know what level is either. If you have the board trimmed out properly to fly in the air, and set it on unlevel ground, it will take off in the direction it is tilted toward until you correct it's position with the sticks. This board is based on the original KK board with piezo gyros (read above who royalties are paid to) and the KK board is just another step toward making a better board where this is an earlier version. However, this board can be made to fly quite stable if you take the time to tune it correctly. Hope this helps and Happy flying!

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!!!.
