Item Code: MD021

The autonomous power supply module is a combination of two devices – a lithium battery charger and a 3V to 5V step-up converter, which is suitable for powering 3V and 5V devices: Arduino controllers, Orange Pi and Raspberry Pi mini-computers, and others, as well as charging mobile devices, acting as an autonomous power source.

Battery connection – parallel.

Attention! Strictly observe the polarity of the charger and battery connection! If connected incorrectly, the device is guaranteed to fail!
