This module, based on LM2576 5V regulator, lets you provide power to 5V USB devices from a wide range of power sources. Use it to power up your raspberry pi and similar usb powered devices and fast charge your cell phones & power banks, using Lipo batteries, power adapters or similar dc power supplies.
Power Inputs: There’re 3 options to apply input voltage: one xt-60 lipo battery connector, a barrel connector for power adapters (center positive) and a terminal block connector (alternative input). Note that there’s no reverse polarity protection. And be careful to use only one of them at a time to supply input voltage. Power Outputs: Three USB-A ports as well as a three pin output power rail to supply clean voltage of 5V to any device of your choice
Max output current (all usb ports & power rails combined): 2.5A. It’s recommended not to exceed 2A continuous current.
