The next evolution of the rotor revolution is here!! The KK-mini is packing all the same power, but with a new mighty-mini form factor.

The KK-Mini is the next Big/Small evolution of the first generation KK flight control boards. The KK-Mini is based on the KK2.1.5 architecture and has all the same inputs and outputs as well as the full functionality of its big brother. The new 36mm designed was adapted to fit the needs of the new mini market, but don’t let its size fool you as it's just as much at home in any size multi-rotor. The KK mini still utilizes a built in GUI using a hi-res mini LCD and 4 micro buttons for the same great KK experience. It was engineered from the ground up to bring multi-rotor flight to everyone, not just the experts.

A host of multi-rotor craft types are pre-installed, simply select your craft type, check motor layout/propeller direction, calibrate your ESCs and radio and you’re ready to go! All of which is done with easy to follow on screen prompts!

The original KK gyro system has been updated to an incredibly sensitive 6050 MPU system, making this the most stable KK board ever and allowing for the addition of an auto-level function. At the heart of the KK-Mini is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An additional polarity protected header has been added for voltage detection, so no need for on-board soldering. A handy piezo buzzer is also included for audio warning when activating and deactivating the board.

The KK-Mini added polarity protection to the voltage sense header and on-board buzzer. The voltage sense line has been updated for better accuracy.

If you’re new to multi-rotor flight or have been unsure about how to setup a KK board, then the KK-Mini was built for you. The 6 Pin USBasp AVR programming interface ensures future software updates will be quick and easy.

(Custom Mix via the "Mixer Editor" option)

The Mixer Editor allows you to adjust where and how much signal the motors receive from stick input and sensors. This allows you to create any configuration possible with up to 8 motors or servos.

Customer self-update function.
Satellite input use Satellite-to-CPPM converter (#24524) at throttle channel(need steveis SW)
Sbus input use SBUS-to-CPPM converter (#52185) at throttle channell(need steveis SW)

** Note: It is all ways recommended to update to the latest software version as part of your initial setup.(This is different than v1. 6 for KK2.0)  

*** Note: The KK-Mini uses the same firmware as the KK2.1~2.1.5 series

I just installed the KK Mini in my tricopter. Everything works fine except that there isn't any power going to the servo. I measured the voltage on the pins going to the servo and it's 0 volt. Can anybody tell me how to fix this ? Hobbyking should make some sort of wiring diagram or manual available for the KK Mini.

Have you checked out David's site, he has an excellent video on tri-copter setup.... both the KK-mini and KK 2.1.5 When you say everything is working fine..... is RX being powered directly from board (ECS is feeding M1 output) and your able to arm system to spool up motors?

Look at bottom of pg for www.link

It is not allowing me to post link to video??????? Google RCExplorer and search tricopter V3 kit and he has YouTube videos

Thanks Rejean for your reply. It seems that one has to use the power of two ESCs, one to power the KK Mini and the rx and the second to power output channels 2 to 8. I didn't know that and only used one powersource on output channel 1. On the two other ESCs I removed the red wire from the plug because that's what it says in the KK 2 manual. So now I replaced the red wire from ESC 2 and it works fine now. Thanks a lot for your help

If the buttons on the board are not working it sounds like you have a faulty board. Fill out an RMA and then send it back to HK

Well, Now I suppose I'll be getting one of these to make an even smaller mini acro quad. Ha ha!

ISP connector JP1.....does anyone have any accurate info on pin layout? Board held vertically with buttons at the 6 o'clock psn.....is Vcc pin upper left or lower right? I've exhausted my search on the net, lots of schematics for the KK2.1.5 board but I have yet to find info to confirm proper ISP hook-up for this mini board. Board checks out ok....but I want to install Steveis' latest firmware 1.19

Do an Google Image search for "kk2 isp pinout"
 Rooster911 620 points
Sorry, that's for the normal size KK2... i'll see what i can find on the mini...

Vcc is upper left....I've uploaded a picture of pin layout....it was the same as its larger brother 2.1.5

nice fc, I use it in my 250mm blackout clone and fly very well, stable and easy to setup, but I had to mount it using the rubber specers to isolate the best vibrations. Only use screws and nylon spacers! however uncomfortable for the buttons and the LCD on this frame type

This is smaller than you initially think from the picture. Even the LCD is significantly smaller than the original KK2. You almost need a magnifying glass to read it!

I bought this board for my new built 250 Quadcopter. With this mini board my little Quadcopter is flying very,very stable and easy to fly. I have not found a manual but I have used the manual for KK2.0 to setup. The pins for receiver and ESC are described directly on the backside of the board. ( other as at KK 2.0 board). On my quadcopter i have used 4 peace zmr 1804 KV 2400 - motors and 4 10A ESC with simonk-firmware and propeller 5030 (3 blade). Weight of all parts and 800mA Lipo is 275g. The KK2.1.5 mini works very good - better than my KK2.0. Thanks for this nice product.

This thing is super-small! I bought it for my FPV 250 Spec. I will check the programming later and give more review. Just wanna make sure that if you guys are buying the FPV 250 Spec, you actually need the standard size KK2.1.5, although you can still use this one.
