Different powering up methods for your board

There are 3 methods to power up the board. You can pick any, but we'll tell you which method is more convenient for each stage of your project. These methods are:

  • Using a USB cable to connect it to your computer/laptop.
  • Using an AC-to-DC adapter supplying 7-12V to the power jack.
  • Using an external battery to supply 5V into the Vin pin on the board.

Powering Methods

USB cable​

In this method, all you need to do is connect the USB cable to the board and your laptop as shown in the following pictures. Your laptop delivers the 5V the board needs for power-up and for the inputs and outputs connected to it as well.

Micro USB

Adapter​

The adapter is another method of powering up your board. You'll need an adapter with 2.1mm connector that supplies the board with 7-12V to avoid overheating of the voltage regulator. The regulators on your board work on converting 7-12V into the 5V and 3.3V the board needs for power-up.

Jack

Vin pin​

The Vin Pin method is mostly used when your project is on-the-run. If you're making, for instance, an RC Car that needs to be powered-up and moving at the same time, you'll need an external battery delivering 5V into the Vin Pin. The ground of the battery should also be connected to the ground of the board.
