PicoBuck Hookup Guide
Developed in collaboration with Ethan Zonca of protofusion, the PicoBuck is a small-size triple-output constant current LED driver. By default, each channel is driven at 350mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board.
Here are some topics you should know before using the PicoBuck. Have a look if you need more information.
