HobbyKing™ KK-Mini Multi-Rotor Flight Control Board 36x36mm (30.5x30.5mm)

HobbyKing™ KK-Mini Multi-Rotor Flight Control Board 36x36mm (30.5x30.5mm)

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 bought two of this and I couldn't get receiver signal. At best, I could get CH 1 and 2 from one KK2.1 and non from the other. I know for sure receiver binds correctly by checking servo movement. Anyone can help me? I 'm using Orange receiver without CPPM. I don't have a receiver with CPPM output. Anyone tried with receiver input and works? How?

How do you wire it using oslo ESC's if only the first M1 transfers power?

The X4R-SB manual says that by jumpering the Channel 2 and 3 signal pins upon binding, channels 1 thru 8 will output cppm. Do we still need an sbus to cppm converter. If so do we need the Hobby King ZYX cable or the Frsky cable? Or, after jumpering ch2 & 3 on the X4RSB can we connect a cable from the Sbus pins on the X4R-SB directly to the fhrottle channel on a Stevis 1.19S1 flashed mini KK2?

I want to use a Frsky X4R-SB receiver with this board. What does #52185 mean. Which cppm to sbus converter do I need?

Does anyone know of a KK2 Mini board with connections exiting from the side of the board rather tan from the the top of the board

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.
