Quadcopter Using KK 2.15 Module




For a drone to fly autonomously, all the necessary sensors, processing power, and communication chips must be built-in. While that may not seem like much, it actually eliminates a lot of currently existing commercial civilian drones available to the general public.

NOTE: This Instructable has been entered for the Coded Creations, Move it, and Things That Fly Contests,if you love this project and appreciate my efforts, I would be highly grateful if you could vote for this project there and help me win.

Step 1: Materials Used

Hardware Items:

1) Quadcopter Frame (Preferrably one which has a built in Power Distribution board)

2) Microcontroller (KK 2.15 Flight Controller)

3) Electronic Speed Control (30 Amps) (4 pieces)

4) Brushless Motor (850KV) (4 pieces)

5) Propellers (2 sets)

6) Power Distribution Board (Not needed if frame has a built in one)

7) Lithium-Polymer 2300 mAH Battery

8) FlySky FS-T6 Controller includes the Receiver


9) Stress balls (4)(Extremely useful if you are a novice flyer like me)

Tools and knowledge:

1) Basic soldering skills
2) Alan keys
3) Shrink tubes(Preferably Turnigy)
4) Zip ties (To hold the ESC's onto the frame)
5) Glue gun (To put all over the connections to avoid any contact between them)

Step 2: Assemble and Connect

1) The motors and ESC's can be connected to each other via direct soldering or using Bullet Connectors of 4mm dimension.

2) The ESC's are then connected to the power distribution board, or in this case directly to the frame which has an inbuilt power distribution board, by soldering. (Make sure to know if the ESC's are supposed to be flashed or not, mine did not required to do so.)

3) Once this is done, solder the battery wire to the frame.

4) Once all the soldering work is done,and the hardware is setup, connect the KK Board(again flashed with the latest firmware) with the ESC servo wires, and Receiver.

Step 3: Plug in the Battery and Test Your Quadcopter

1) If your code is all correct and your connections are all good you should see the LCD screen on the board lit up, from where you can easily calibrate both the Accelerometer and Magnetometer.

Exact steps to be followed for the setup

2) Connect the controller to your laptop and download the T6Config application on to your desktop and test the controls to see if the Throttle, Pitch, Yaw and Altitude are not inverted.


3) Set End points to 100% and subtrim each channel according to your needs and quad's stability.

4) Now arm the KK Board(you'd see ARMED come up on the LCD screen) and gradually increase the throttle. If everything is perfecty connected, flashed and calibrated the motors will start rotating.

Step 4: First Flight and Future Improvements

I attached the Stress balls, to ensure in the event of I having to cut the throttle at any instant, the landing wouldn't destroy any of the parts or the frame.

While this whole task took me 2 days, there is still room for improvements like controlling the quadcopter with a mobile device rather than a remote.


When I will upgrade my quadcopter with FPV (first-person view), i.e. equip my quadcopter with a camera, video transmitter, video receiver and goggles/monitor to have a live video feed down to the ground, which will also mean purchasing a battery of much higher capacity than the present one.

    I have an issue with kk board its LCD screen is not working properly . I need help

    Hello sir, I followed all your instructions, calibrated esc's and also accelerometer but my quad flies sideways rather than flying vertically. please help me to solve this problem!!

    what youre describing is called "drifting". your quad thinks its level but its really not. recalibrate the gyroscope on a level surface. even out the weight of the quad. you may have to move some things around. shift the batteries to the off balance side. hope that helps.

    My quad also fly side ways . It lifts high but it is not stable at a position. Please help


    Reply 3 years ago on Introduction

    Also the most common mistake people make is not keeping the sticks of the RC in the center position, so look into that as well.


    Question 2 months ago

    I have kk 2.15 flight controller. I have tried every hook and crook but my Quadcopter is not stable. I am struggling for 2 months now . Please help.


    Question 3 months ago

    Will the length of wires effect the drone? If one is a little shorter or longer than the other motor esc connections, will it effect the quads performance?


    Question 4 months ago on Step 4

    See my quadcopter is not lifting when I try to give full throttle then all the motors stop rotating and when I see the kk2.1.5 board it showsitself armed

    I do the same satting in kk2.1.5. But two motor are spaning and other two not. why Do so. Give me staps and sutable Ans.


    Question 1 year ago on Step 2

    We have not got Bullet connector for connection moto with ESC , so can we solder them without any harm to kit??

    Answer 7 months ago

    Hi. You can solder them, no harm. It might be bit late now, but this ibfo might be helpful for others.


    Question 1 year ago on Step 3

    Is the kk board available in the market already coded?


    How much is the weight of the quad-copter? Will it be able to handle additional weight?

    hello sir , can you please teach me how do i put wires in correct slots from my kk 2.1.5 to the same receiver which youve used ? please do help me :( please

    A few questions rbanga.. Is there much programming involved? Could an arduino be used as a flight controller? Did you attach the stress balls using zip ties?
