This module is a compact DC-DC step-up converter circuit designed to create a DIY mini UPS for devices like routers or CCTV cameras. It takes a 5V input to both power the output and charge a connected 3.7V lithium battery. When the main 5V power is lost, it automatically switches to the battery and boosts its voltage to a stable 9V or 12V output. It’s a simple board for ensuring your essential small devices remain powered during brief outages.
