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.

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)

I need a replacement lcd screen. ..!! Plzz help!
nathan  31 points - 4/22/2015
what are the prongs at the top of the board for?
 Rooster911 692 points
Its the ISP connector. you can use it for flashing the board with different firmware.
Nicholas  1 points - 4/17/2015
I am trying to build a tricopter with this board and I have two problems with it right now one being that when I give it power the screen lights up but it does not display anything. I need to be able to set it up as a tricopter on the board. Second issue is I don't understand how to plug this board into the receiver. Can anyone help me with this?
 Rooster911 692 points
See video...

I will watch this more later but i have a KK mini and the left side only has one pin. What do I do?
 Nicholas 1 points
Also my screen is coming up blank and I dont know what to do.
 Nicholas 1 points
I see that it explains the wiring for the mini as well thank you that helps. Do you have anything on the blank screen though?
 Rooster911 692 points
It could be a faulty board. Make sure you wired the board correctly. On the right side connectors, ground to the outside and positive to the inside (closest to the screen)

I got the board to display the menu that video is very helpful. I just cant get the motor one to turn on and the throttle wants to keep to the left. Any clues?
 Nicholas 1 points
So update if you guys dont mind still helping me out. I got the board to light up and display right I got all the receiver functions to work right. It was able to arm yesterday and I got all but one of the motors to spin. The rear motors servo wants to pull all the way to the left and the motor that wont turn on's (front left) ESC is just lit up red. It did that yesterday and it feels hot. Today it wont arm at all.I dont know why. Can anyone be so kind to help?
 Rooster911 692 points
Check if you have the right motor layout and allso check the the sub-trims and (see video) Do acc calibration and ESC calibration (again) Make sure the servo was in the centre position when you installed it.
 nathan 31 points
ecan you make a video of the issue showing your wiring and post it up?
 Nicholas 1 points
I will do that tomorrow. I do not have it with me. I want to ask one or two more questions. I will work on it tomorrow and if I still have an issue after that I will make the video. How do you do an ESC cali? I have not seen that option. Also when all ESC are plugged in the two with the working motors will light up solid green the one that did not work is lighting up a flashing red. I talked with a tech support and they said it sounds like it might have burnt out or had a defect. What do you think? Ive tried plugging the ESC in question into other motors and it will still show up red while the other ones whill be green. It will not arm anymore. Idk why.
 Nicholas 1 points
So I plugged it in today to be confronted with a new problem. Now not only would it not arm it comes on and then the screen goes blank. I have messed with the wiring. IT now just goes blank for no reason that I understand. I think the board might be fried. Or the ESC is fried and just now broke the board. I cant get the screen to stay on long anymore. I think I'm to the point now where Im jut going to put in an order for a new board and a new esc. Thank you for all your help wish me luck.

I have no idea how to wire this using common wires? pics anyone?
 Rooster911 692 points
See the video above.
 Antonio 12 points
thank you for posting the video but the mini does not have all of the connections to go to the receiver. do I only hook up the signal part and leave the other two wires not attached to anything except for a throttle?
 Rooster911 692 points
Yes, the receiver needs Positive and Ground only once (they're all connected inside the receiver anyway) Also watch the video, at 3:00 min. Where David shows how to connect the MINI KK
 Antonio 12 points
I did the throttle arm where I set full throttle and press buttons one and four. motors only spool while these buttons are pressed and pass through is on. as soon as I release the buttons, motors won't respond.
 Antonio 12 points
apparently I have to arm the kk by hitting full right rudder. this takes it off safe and allows power to the motors.
 Rooster911 692 points
That's correct. You can find a manual on the description page of the "Hobbyking KK2.1.5 Multi-rotor LCD Flight Control Board", under the purple "FILES" tab. The KK2.1.5 and the Mini-KK operate in exactly the same way.

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.
