BREADLED is a breakout board for WS2812 addressable LEDs, designed to fit perfectly into common breadboards and perfboard without taking up an excessive amount of space.
Boards are shipped panelized and without headers installed, to simplify shipping. All SMD components are soldered, so all you have to do is snap the boards apart (optionally you can file down the edges too) and solder on the headers.
