Compact USB power module

This JacobsParts boost module converts a 2.25 V to 5 V DC source into a standard 5 V USB charging port. It suits engineers and hobbyists who need to power USB devices from single lithium cells or dual alkaline and NiMH batteries. The board delivers up to 1.5 A peak and 1 A sustained current with up to 96 percent efficiency. An onboard LED indicates when the output is active.

Solder-in installation notes

The 28.9 mm by 18.8 mm PCB mounts by soldering wires or headers to its through-hole pads. Solid-state capacitors and a -40 °C to +85 °C rating suit industrial environments. Ensure the input source can supply sufficient current for the 500 kHz switching regulator. Incorrect polarity or an undersized supply will prevent start-up or trigger protection.

Pre-order checklist

Verify that your DC source stays within the 2.25 V to 5 V input window under load. Confirm the target USB device draws no more than 1 A continuously or 1.5 A momentarily. Check that the 8.5 mm profile fits your enclosure and that wiring can handle the peak current without excessive voltage drop.

Questions about this item

How can I confirm the boost module is operating correctly once installed?

The on-board LED power indicator lights when the module receives a valid input between 2.25 V and 5 V and is producing a regulated 5 V USB output.

What comes in the package and what extra items are required?

The module itself is supplied; you must provide a 2.25-5 V DC source such as a 3.7 V lithium cell or two alkaline or NiMH cells and a USB cable for the device you want to charge.

Which input voltage range suits a single 3.7 V lithium cell versus two alkaline cells?

Both a single 3.7 V lithium cell across its full discharge range and two alkaline or NiMH cells in series fall within the 2.25-5 V input window, so either works without a different version.
