KK 2.0 board

[xx_arnie_xx]

Hi
I am finding difficulty in connecting servos to kk2.o multicopter board, help me........

[parichya.gautam]

same thing is happening to me , but nothing is working out ..

[rastsaurabh]

servos to KK2 never heard this....where would you use servos for in a multicopter.

do search & read about your query on this forum.

Fortunately ... read here http://www.rcindia.org/multirotors/tutorial-how-to-build-multirotor-from-scratch/msg150191/#new

Plus VTOL too is there ..

What is your problem with connecting servos to kk2..?
Please describe your problem..
Rastsaurabh:  tricopter need servos for yaw control.. Even you can connect servos in all the output pins and check the working is correct or not...

[rastsaurabh]

hmm Fantastic...... Saw this first time

1st saw quad with reversible motor
then this... great  possibilities are limitless.

[parichya.gautam]

coming back to my query ... any way to do so ?

[pravesh736]

Connect servo plugs into right side of board which has 8 output rows of pins. Black wires always connect towards the outer side of the board.

[chetanmayekar]

it might be yconnector used for all channel.. see without propeller running he can not move servo..

kk2 has only 4 ch input from rx.

We are planning buid a VTOL based rc plane...........bt when i connect the servo 2 the board(kk2.0) it wont respond(servo)....  

[arun.sreelakam]

I think servos must connect to the receiver directly... using 3 y connector in to one channel... so that the movement is possible right?

What signal is the servo suppose to respond to ? Tx input or kk2 gyro/acc stabilisation?

You need a BEC for servo to work from connector 2 onwards to 8. If you are not using a ESC with BEC in any of the connectors 2-8 then there is no 5V in connector 2-8 for the servos to wk.

[parichya.gautam]

connected servo to the rec. and it worked !

I intend to use kk 2.0 on an rc plane for stabilization with openaero2 fw,  so can i use another ESC to power 2-8 pins or does it have to be an UBEC? I have a 30amp esc lying around.

you can not connect servo in M1 connector because thats the port which gives power to the kk2.0 board.
you can use servo in M2 to M8,
The M2 to M8's 5V power pin is connected together, and any servos here can be supplied by any ESC which you can connect to any free connector.

Question asked in this thread sounds very interesting to me.

I did little research and here are my findings.

1) Servos are connected to M5 to M8 (see attached images)
2) Mixer Editor option might be used ... that allows mixing like radio
3) There are some H/W modification done on the board. i.e. Alarm is added + some more (see attached images)
4) Firmware is 1.4 but may be customized
5) ADA : Anologue devices acceleromrter is also used.

Thank you,
Atul

for mixing example see

[atulrajguru9]

In above you tube page check his comments. he said

"chippi09 2 :
I start at 2 servos to see it fly,maybe 4 later and then 6 but,need some careful custom mixing on miixer editor. Need to split motor signals to get 6 motors and 6 servos to work....later bro ,I'm getting a headache !!!"

Now i am 99% sure that its mixing!
