The Hobbyking KK2 Flight Controller
5 Attachment(s)
Among the many KK2 threads started after this, the official KK2 thread managed to migrate to here.

I feel this thread should be dedicated to builds, custom mixes and any unique or advanced uses of the KK2 such as custom firmware or ports of existing software.

what could be the all up weight !??.
Is this a product for noobies who can't be bothered to read flashing LEDs ?.
If so, it's just what I need for my son.

I have seen that too.
However i cant quite figure out all the PINs, as on the Left Side y ou have 5 Sets of 3 Pins and below 2 more rows, on the right Side you have 8 rows, so it could be either up to 8 Motor Outputs on the right side and 5 Channel inut on the left side and 2 outputs for maybe a Camera-gimbal.
However if i use a Gimbal i would also like to see Inputs to adjust the Gimbal in flight to get a different Angle of my aerial Shots/Videos..

Well lets see what HK is offering in this Package.
The 2 Pin i think 1 may be for a low voltage alarm/buzzer.

I am still waiting to find out some more info about the new Heavy Lifter Frame they had announced in a Newsletter last week.... but no Pictures were included

I'm guessing/hoping that the six pins on the lower left are for JTAG/SWD programming. The two-pin header is likely for battery voltage detection but there should also be a buzzer output unless that's underneath.
It they have any sense they should include a CPPM input so that you can have 8+ RC channels in.

interesting... it does look more like a mwc than kk

#7 empire007 Jun 06, 2012 03:59 PM

I really hope that if it is a Multiwii clone they release the source. I'd hate to have to stop buying their batteries on principle.

Hi Guys, here you got perfect solution for MW controller with all addiotional options you can imagine with very resonable price. I post it as I am fun of our domestic made solutions
I know hunderds of people using this with huge success and fun! So dont waste your time waiting for KK2, just jump and be in touch with the author for making deals.

#9 timecop Jun 07, 2012 04:54 AM

lol yeah, except if people wanted a 8bit multiwii board, they could have just got them from goodluckbuy for 30-50$

#10 titeuf007 Jun 07, 2012 05:20 AM

no evolution !!!!!
they should waiting and create a 32bit multiwii board with great sensor

#11 LazyZero Jun 08, 2012 12:23 AM


There is a new photo of KK2 out on twitter. But can't identify anything on it.
On the left side second board from bottom you can guess it has a ATMEL print on the controller.
EDIT: If I counted correctly 44 legs. It could be ATmega1284?


#12 timecop Jun 08, 2012 12:27 AM

That doesn't look like 48LQFP... That's a 44TQFP... Maybe some atmel ARM chip?
Or maybe AVR XMega lulz

#13 titeuf007 Jun 08, 2012 01:29 AM

seem to have only gyro and acc and perhaps compass!!!

HK doesn't do evolution (or revolution) - just look at KK board and the 'new' i86 board (=Eagle clone)
