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

How do you wire the voltage sensor?
 jonathan 12 points
Hi, Just plug a POSITIVE wire from your power distribution board to the red pin of the KK mini. target=_blank>

Does the voltage sense wire from the red pin connect to the positive battery terminal?
 jonathan 12 points
yes. You can also plug it to a positive output on your power distribution board.

And the ground is done through the board I presume. That is an easy hook up. Thanks for the info.
 jonathan 12 points
That's it. You're welcome

Hi could you make this auto leveling just by releasing the sticks? instead of the other options ?
 Rooster911 667 points
That's exactly what happens when you fly in self levelling mode.

Couldn't I solder the 5V gap between M1 and M2 to supply power to the tilt servo in a tricopter configuration? I have ESCs without BECs and a seperate BEC on M1 to power the board.
 RC911 51 points
I wouldn't bridge the two power buses if I were you. Doing so could make your copter fall out of the sky due to servo noise. Servos are known to produce noise on the power bus and this can reset the controller. Use a second UBEC to keep the power buses separated or get ESCs with internal BEC.

For those wanting ppm. It is not like the kk2.1 the connection is different (maybe the same for spektrum but different for frsky. you need on the left hand side where you receiver is connected (looking from bottom of board to top) ground, power, nothing, signal a pain because you have to pull the signal lead out of a standard 3wire jr plug to connect it to the next pin.

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.
