The Kitronik LED Strip Kit offers a great way to learn basic electronics. As requested by some of our customers, this kit is similar to the white USB LED kit but incorporates multiple LEDs. Once built, it offers a great platform for designing custom enclosures for low-power lighting. The kit includes 4 LEDs, an on/off switch, and a PCB which has a shared current limiting resistor and USB connector already mounted to the board. Only the 4 x LEDs and the on/off switch need to be soldered by the maker.
