Description

This is a 5V UPS module that combines a Lithium Cell Charger and Step-Up Converter for a single 18650 Lithium Cell. It provides a 5V output voltage to supply up to 1000mA of continuous current when the 5V USB power supply is disconnected or unstable.

The UPS-Function can be very handy to continuously power electronic circuits when the input voltage is unstable or interrupted.

If the output is only required temporarily (on demand), a switch can be connected to the pads marked with P5.

To charge the cell, a 5V power supply (min. 1A recommended) must be connected to either the USB port or the 2 pads marked with 5V- and 5V+ right to the USB port.

The 2 solder pads [+] and [-] on the edges in the middle of the PCB are directly connected to the Lithium Cell and can be used to connect our Single Cell Lithium Battery Gauge EAN 4260474034536 (blue) or EAN 4260474034550 (green).

Finally, the 2 solder pads marked with UPS- and UPS+, are the 12V Output. The maximum continuous current available on the output of the 5V UPS is 1000mA.

There are 3 LEDs on the 5V UPS Module, showing the following information:

LED D2 (green) shows 5V output active
LED D3 (green) shows the full charge state
LED D4 (red) shows the active charging function

Notes:
– Wires and the battery holder need to be soldered to the circuit board.
– For the always-on function, the jumper P4 can be closed with a drop of solder.
– A bigger capacitor (e.g. 1000µF) on the output can help to avoid continuous booting of a connected MCU or WiFi module.

    I’ve picked up a few of these now and they’ve been fantastic so far. They work well as a UPS for microcontroller projects and some low-power Raspberry Pi projects. Do yourself a favour and look at the image that shows which terminal is +ve and which is -ve and then write it on the PCB with a marker before lining up the battery holder (which has small + and – signs on it) and soldering it on!
