### DESCRIPTION

This board is designed to charge 1 li-ion battery with 3A current performed on TP4056 chips. With good cooling through the thermal padding it is possible to increase the current to 4A. Or else you can adjust the current to 2A, reducing the board's heating to a minimum.

For example, this charging is suitable for fast charging LG HG2 18650 (charge current 3A max).

Non-standard application of this board is an LED driver for direct current.

### TECHNICAL DETAILS / COMPONENTS

Assembly parts:

- 4pcs TP4056 

- 4pcs 0805 resistor    (1.2KΩ - current 4A - only  heat sink, through thermo-laying)

                                       (1.5KΩ - current 3.12A - desirable heat sink, through thermo-laying)

                                       (3KΩ - current 1.6A - no need heat sink)

                                       (other current see in datasheet  TP4056)

- 7pcs 0805 10uF or more ceramic capasitor (6,3v on more)

- 1pcs 0805 - resistor 1.2KΩ 

- 1pcs 3528 SMD RGB LED or  any led to LED out pins.
