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.

Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a switching power circuit that raises a lower input voltage to a higher output voltage. It is used when a device needs more voltage than its power source provides, for example running a 5 V sensor from a 3.3 V supply.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
