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

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.

how to bind the main control board fcs 400 with transmitter of devo 7
2Mylent  1 points - 2/20/2015
Hello, I would like to update the firmware of the Mini-KK, but I do not know how many ISP connect the cable on the card (diagram). The image "6 pin ISP layout 'in the" Files "forwarding on a 404 "Page no longer available". Someone could tell me how many ISP connect the cable? Thank you in advance.

so i have my trifecta and i got nearly everything complete but the kk2 mini how do i power it on does anyone have a power guide or something. this is my first build. ive got the receiver and motors connected but the flight controller doesn't turn on am i suppose to wire that in directly to the board? if so where? thank you for your time.
 Rooster911 653 points
You need ESC's with internal BEC's. The KK is powered through M1. You also need power on M2 and/or M3 to power your servo.
 MICHAEL 2 points
so me having a afro slim wont do it? and if not then what can i do? i have three afro slims.
 Rooster911 653 points
You need a separate BEC to power your receiver. The KK wil the get his power from the receiver (through the ground and vcc at the input side) You also have to provide power to one of the connectors M2 to M8 (They have a common VCC and ground) for your tilt servo. So plug in a separate BEC to your receiver and to, for example M5, and it should work fine
 MICHAEL 2 points
So I purchased a BEC do I just somehow split the red and black into M1 &M2?
 Rooster911 653 points
That wont be very practical, best you split de BEC lead to an free connector of your receiver and to a free connector of your kk2's outputs m2-m8 (with a tricopter M1 to M4 are already taken so you choose M5)

This flight controller is great. I started my tricopter build trying out the naze 32 acro but i had trouble just getting the thing to connect to the computer to program it. After about 2 weeks of trying that I ended up giving in and taking the loss and trying the kk mini for the first time since this was my first triopter build i thought i might try new things. This made the setup, programming and adjustments of the tricopter incredibly easy. It will take a lot to get me to change from this small cheap board, but this is high quality highly recommended. Got the tricopter flying in less than an half an hour with this board.
 RonRC 4001 points
TannerB, Awesome! Post some video of your build if you can. Would be great to see it. I'm currently building a powerful and large T-tricopter for longer, stable video. All the best and Happy flying!

i apologize for asking to many questions but i have one more well i got all the motors and the fc working but when i fly the copter it does'nt fly straight, and one of the motors usually get overpowered may someone please help.
 Sim69 9 points
Search for "THE NEW KK2.1 & KK2.1.5 FC Owners Thread" It relates to the full size board but will still help you set up your mini. There are two manuals in the first post. Would be nice if Hobbyking would include some basic instructions for the 'mini' especially for people who are buying their first KK board :-(
 RonRC 4001 points
Hi jr, can you post some video of just what's going on with your multirotor? That would help tremendously for diagnosing what issues you are dealing with. All the best and Happy flying!
 jr 3 points
here is the video i think this is called drift but anytime i try to get my quad airbone it automatically starts going to the right i put all the trims to zero did he acc calibration, and calibrated my esc i don know why it wont fly sriaght up im not touching another stick either besides the throttle
 jr 3 points
im not sure if the video sent please tell me if it did, and thank you for the manual sim69
 RonRC 4001 points
jr, it didn't show. I log into my YouTube channel, select [video manager], find the video I want to post and click on the [edit] button. When the edit page for the video comes up, off to the right you'll see "Video URL: [*****************-]. Select and copy this URL and paste it in the Youtube File window. Hope this helps and Happy flying!

im not sure what is wrong with this website i send the video and the link several time but it never shows so ill just put it in between the parentheses thank you please help
 RonRC 4001 points
Not sure jr, what is your youtube page and I'll look it up to see what the issue is with your multirotor.

Drone drifting problem kk mini thats the title
 RonRC 4001 points
jr, watching the video, it appeared like the motor and prop in the lower left of the video were spinning in the wrong direction. I couldn't be for certain but if you would remove the prop, put some tape on it and check the rotation, that may be the problem. If that is it, should be an easy fix to reverse the motor. Hope this helps and happy flying!
 jr 3 points
i cheeked but everything is rotation the right way but i dismantled it again and put it back but i still have the same problem
 RonRC 4001 points
Put it in Autolevel, hold it in front of you and give it just enough throttle to make the props spin. Be very careful while doing this. They should all be spinning evenly when it's level. If not, set it on a level surface and calibrate the accelerometers again.

i just decided to do a factory reset, and it work i think it was the pi settings im not sure, but thank nyou for te help
 RonRC 4001 points
Awesome! Post some video of your quad when you get a chance. Here's my little micro quad. I plan to build a smaller one with one of these boards as soon as my shop is completed.
 jr 3 points
that quadcopter is great hand it goes very high, and also nice acrobatics thank you for all the help, but i have encountered the same problem again but this time the air craft moves backwards when its lifting off idk whats wrong anymore it is suppose to fly straight up when you move the throttle right? and also my channels are reversed could that have something to do with it or do i need to fly it outside?
 jr 3 points
could a loose arm also be a problem think i may just factory reset again though
 RonRC 4001 points
A loose arm could affect it but you may want to get it out over grass and try to pop it up off the ground. The ground effect may be causing some issues for you too. Have you had it up in the air to see which way it drifts? Understandable to be nervous and not getting it more than an inch off the ground but at that point, you will have lots of ground effect (turbulence from the air being pushed to the ground and coming back under other props).
 RonRC 4001 points
Oh and if your channels are reversed, ensure they are correct by reversing them so you can fly normally. Make sure when you push the right stick forward, the rear motors spin up, to the left and the right motors spin up, and when you yaw on the left stick, it yaws in the correct direction. If not, you need to reverse your transmitter's pitch, roll, or yaw.

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.
