This compact DC-DC boost converter steps up input voltages from 2.5V to a selectable output of 5V, 8V, 9V, or 12V (default 12V) at over 80% conversion efficiency. Two solder pads (A and B) on the front of the module allow you to configure the output voltage — refer to the markings on the back of the board for the correct pad configuration.

An onboard power indicator LED shows working status at a glance. The small form factor makes it easy to integrate into battery-powered devices, LED lighting, and portable electronics.
