*Suitable for microcontroller power supply, 5V1A can meet the requirements of most development boards.
*Suitable for Raspberry Pi power supply and can be used as UPS power supply, but peripherals should be reduced to avoid insufficient power supply current.
*Suitable for power supply of low-power projects, small size and compact layout, can be easily embedded in the design.
*The project uses LED lights as status indicators: green light flashing => charging; green light always on => charging completed; red light always on => discharging; red light flashing => low battery.
*The project can replace tp4056 for charge management of lithium batteries, and eliminates the need for a 3.7v->5v boost circuit.
