Pack of ten step-up boards

This pack contains ten identical mini boost modules that raise a single-cell lithium battery voltage to a selectable 5V, 8V, 9V or 12V rail. Each board measures 22 by 11 by 3.6mm and is intended for DIY electronics projects that need a small, fixed-output supply.

Solder-jumper voltage selection

The output level is set by bridging two pads labelled A and B on the PCB with a soldering iron; the default configuration ships as 12V. Changing the jumper pattern lets you match the rail to 5V, 8V or 9V without adding external components or reprogramming anything.

Current limits and LED draw

With a 3.7V lithium input the module delivers up to 1A at 5V, 0.7A at 8V, 0.6A at 9V or 0.5A at 12V, provided neither input nor output current exceeds 1.5A. The on-board LED draws roughly 6mA at the default 12V setting and can be disabled to reduce quiescent current. Builders needing more than 1A continuous output or a wider input range should look elsewhere.

Questions about this item

What are the board dimensions for fitting inside an enclosure?

Each module measures 22 mm long, 11 mm wide and 3.6 mm high, so allow at least that footprint plus clearance for soldered wires.

How do I change the output voltage on the module?

Use a soldering iron to bridge or open the two pads marked A and B on the PCB; the silkscreen table shows 00 = 5 V, 01 = 8 V, 10 = 9 V, 11 = 12 V.

Will the on-board LED drain my battery during long-term use?

With the default 12 V setting the indicator draws about 6 mA; desolder or cut the LED trace to eliminate that quiescent current.
