TP4056 1A Li-ion Lithium Battery Charging Module With Current Protection-Mini USB

The TP4056 1A Li-Ion Lithium Battery Charging Module – Mini B USB is a 3.7V lithium battery charger module has onboard Mini USB interface. With Mini-USB onboard connector, you can directly connect to computer USB port for battery charging. If USB is not available you can use an external source voltage at IN+/IN- pads, great for DIY projects. It is small size and lightweight. Features Charging indicator: RED LED charging, BLUE LED full Charged Charge Current: 1A (default), modify the onboard resistor to adjust the charging current according to the table below. Use mature charging chip TP4056 for simple peripheral circuits, good protection performance, and high charging accuracy. Fully machinery automated processing, all patch parts manufacturing. Charging current can be adjusted by just changing the circuit board's fixed resistors. It can change the output to the 100mA-1000mA, very conveniently.
