1A lithium battery charging board TP4056 diy

Open source 1A lithium battery charging board TP4056 schematic diagram + PCB (pads drawing board)

1. TP4056 lithium battery charging circuit is very classic, mainly to convert the 5v power of the charger into 4.2V power to charge the lithium battery, the maximum can provide 1A charging current.
2. The capacity of the lithium battery is different, and the charging current is different. Change the resistance of the resistor Rprog (R4 corresponding to the PCB) in the circuit schematic diagram to change the charging current)
3. The red light is on when charging, and the red light is full when it is fully charged. Off green light on.
The charging socket has two options: 3.5mm DC socket and MICRO-USB socket (in the picture below, only the new PCB of the micro socket has added a 3.5 DC socket.







Changing the resistance of R4 in the PCB can change the charging current



. Thank you for watching.
