TP5000 2A switching 4.2V/3.6V lithium battery charger

LiPo and LiFePO4 battery charger module based on the TP5000 chip. It can handle batteries charged with 4.2 V and 3.6 V with a default charging current of 1 A.

On the board there is an LED indicator informing about the battery charge status - the charging mode is indicated by blinking red and green colors, while the green color indicates the battery charge.

0.5 A - 0.2 Ω resistor in place of R100
1 A - 0.1 Ω resistor at R100 (default)
1.5 A - 0.2 Ω resistor next to R100
2 A - 0.1 Ω resistor next to R100

Charging current above 1 A requires additional heat dissipation heat sink.
