This is a 12V UPS module that combines a Lithium Cell Charger and Step-Up Converter for a single 18650 Lithium Cell. It provides a 12V output voltage to supply up to 350mA of continuous current for 12V devices, even when powered by USB and without a lithium cell installed.
The UPS-Function can be very handy to continuously power electronic circuits when the input voltage is unstable or interrupted.
If 12V 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 12V UPS is 350mA @ 12V.
There are 3 LEDs on the 12V UPS Module, showing the following information:
LED D2 (green) shows 12V output active
LED D3 (green) shows the full charge state
LED D4 (red) shows the active charging function
Note: 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.
