Li-Pol TP4056 charger TP4056 single 1S 3.7V micro USB cell with protections
Simple charger for 1-purpose lithium-polymer batteries with a nominal voltage of 3.7V. The maximum charging current is 1000 mA. The system is powered via the microUSB connector or via wires connected to the IN+ and IN- inputs. The module is protected against excessive discharge below 2.5 V and excessive current consumption above 3 A.
Outputs
The module has 6 solder fields and a micro USB connector.
Pin Configuration:
| No: | Pin Name | Description |
| 1 | OUT + | This pins outputs the positive voltage from battery. It should be connected to the circuit which has to be powered by the battery |
| 2 | B + | Outputs positive voltage from USB cable to charge to battery. It should be connected to the positive of the battery |
| 3 | B – | Outputs negative voltage from USB cable for charging battery. It should be connected to negative of the battery |
| 4 | OUT – | This pin outputs negative voltage from battery. It should be connected to the ground of circuit which has to be powered by the battery |
| 5 | IN + | Should provide +5V, can be used if charge cable not available |
| 6 | IN – | Should provide ground of the +5V supply, can be used if charge cable not available |
| 7 | LED Red | This LED turns on while the battery is charging |
| 8 | LED Green | This LED turns on after the battery is fully charged |
