Overview

2022-06-19：

1. Description:

According to the improved design of the original PCB copy board, most components can be moved to the board and soldered.

The hole positions are consistent with the original PCB for easy installation.

Add TP4056 charging chip, the maximum charging current is 1A. If there is a need for larger current charging, modify it yourself.

Integrated DW07D integrated lithium battery protection IC. If there is no need to short-circuit pins 2 and 3 of this chip, there is no need to weld the peripheral circuit of the chip.

With isolation diode, it can be used while charging.

2. Physical objects:

PCB front:

PCB back side:

PCB installation:

Shell treatment:

The Type-C port needs to be enlarged before it can be put down. If it looks beautiful, it depends on your knife skills.
