Note: This tutorial is for the latest version of the FemtoBuck, V12. If you have an older version of the FemtoBuck, please consult this guide.

The FemtoBuck is a small-size, single-output constant current LED driver. By default, the FemtoBuck is driven at 330mA. That current can be reduced by either presenting an analog voltage or a PWM signal to the board. It can be increased to 660mA by closing a solder jumper on the board, as described later in this tutorial.
