I am currently working with a bigger drone that I want to connect with an arduino uno.

The motor and ESC that are already soldered together and connected are these: https://hobbyking.com/en_us/mt1806-brushless-combo-include-esc-5030cw-ccw.html

I have also connected it to a power distribution board where I succesfully can connect my 3s lipo battery.

What is currently missing is where I should put the 3 pins on each ESC onto the arduino board. So there are 12 pins in total.

The color on the 3 wires on each ESC are: yellow, red and brown.

Yellow is the signal if i am not mistaken and those should be connected on the PWM pins where I control each motor in the code.

When it comes to the red it is + power and should I ignore to connect these pins? I would like for my battery to power both the motors and the arduino so of course I would prefer to connect it to the arduino uno if it is possible.

Here are just some clarifications for you:

  • Signal pins don't have to be connected to PWM pins. AFAIK, any digital pins should work.
  • All grounds togheter! Glad you got that right!
  • Connect VCC of ESCs directly to the power supply.
  • Connect power supply to VIn of Arduino (not 5V because you are going to grill it!)


  • Yes, you can probably solder all the VCC wire of the ESCs togheter.
  • By power supply, I meant connecting it directly to the battery.

  • To power the Uno, connect the battery+ to the VIn pin of the UNO.
  • Thanks a lot for the answer! So far so good :) 1. Ok! 2. Ok! 3/4. Do i do the following: Solder all of the VCC of the ESC (the red wire) the same way like I do with the ground and then I connect it to a power supply module? Is this a power supply module I can use? aliexpress.com/item/… It is for a breadboard i think but can it work with an arduino uno? When it comes to powering teh arduino I am a bit unsure how to do it.

  • This is one of my first projects so therefor I am very rookie in some areas!

  • Hi! I was just wondering. I have a 4s battery now that I plan to hookup to a arduino pro mini 5v board instead of a Uno-board. So instead of putting the battery wire to the Vln of the arduino uno I will put it on the "RAW" on the arduino pro mini. Will a 4s or 3s lipo make any difference?

  • Pro Mini's regulators are quiet bad. I'll suggest to put it to a down converter before passing it to the Arduino.
