Item Code: MD020

The standalone power supply module is a combination of two devices – a lithium battery charger and a step-up voltage converter from 3V to 5V and is ideal for powering 3V and 5V devices such as Arduino controllers, Orange Pi mini-computers, Raspberry Pi, and other mobile gadgets, acting as an autonomous power source.

A compact switch is installed on the board to turn off the 5V output voltage. Now you don’t have to unplug the Raspberry Pi’s power cord to turn it off. Three pairs of contact pads, each with 3V and 5V, are provided on the board for connecting additional loads.

Caution! Strictly observe the correct polarity when connecting the charger and battery! Incorrect connection will damage the device!
