There are different ways of providing logic power to your board

Your board needs two sorts of power to work : 12-24V power to turn motors, heat hotends, etc, and 5V ( or "logic" ) power to power the microcontroller ( the brain ).

There are three ways to provide 5V power to the board :

  • By plugging a USB cable in, USB cables provide 5V
  • By soldering a voltageregulator to the board ( and providing 12+24V, which the voltage regulator then turns into 5V )
  • By providing 5V directly to the 5V power input ( next to the VBB power input )

If you want to keep it simple, the easiest solution is just to connect your Smoothieboard to your computer via USB.
