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.

Have bought 4 of these controllers of which 3 are on different frames (1 Rotobits Quad, 1 Rotobits Tri and 1 scratch built Tri)
They work well out of the box and can be configured quickly and easily.
Screen contrast is quite good.
At just over $6, why wouldn't you buy more!

Luce di retroilluminazione

Luce di retroilluminazione display troppo forte. Si vede appena il testo sul display. Non ci sono problemi di stabilizzazione.

Using the firmware 1.6, there is no option to setup the contrast of the display.

Anyway I got my 2 pcs this day - and it´s the same problem.

If HK will post it, you will see (soon) a picture of an older version (guess about 1 year old) showing much better contrast.

Start an RMA and hope you will get a better one...........

good luck

My 1st one had issues with powering up and with blank screen. Hobby king replaced it with a new one and it was perfect. I flashed Open Aero firmware and used it on my bixler 2 with stabilizer and auto leveling mode
