This tiny 3.6V Li-Ion charging board is based on the TP4056 Li-Ion Battery Charging IC. This board is capable of supplying of 1A of charging current at 4.26V to a single-cell Lithium Ion battery when powered via USB or an external source. LED Charging and Done indicators show the charging status.
Solder pads are provided for both input power (if not using the USB jack) and battery output leads.
Charging current can be modified by replacing the SMD resistor located near pin 1 of the TP4056 IC.
This board can charge the popular 18650 Li-Ion battery.
Dimensions: 1"x 0.75" Square.
