I have several old laptop batteries that are not used. I want to use the battery to make several projects. And first I need to make a charger module for the battery. Therefore, in this article I will show you how to make it

Step 1: Watch the Video!!

the video above contains the process of making the module. But there is some information that I didn't show like what components were used to make it.

I purposely did not display this information because I wanted to display it in this article. Besides that, in this article I will also provide several files such as schematics, layout and PCB gerber files.

Step 2: Components Required

below are the components needed to make the modules :

2* micro USB connector
1* 2P T-Block
2* Capacitor 100nF
2* Capacitor 10uF
4* Resistors 1K
2* Resistors 1k2
2* Resistors 0R
2* Red LED
2* Blue LED
2* IC TC4056A
2* 1x2 Male Header
2* Jumper
1* Battry Holder

Step 3: PCB Schematic and Layout

Based on the information that I have mentioned in the video, there is a mistake in the PCB design that I made. These mistakes are:

Pad at the bottom of the IC TC4056A is still wrapped with a Solder Mask
There is one line that I have not connected I have resolved

I have fixed both problems. And for the files that I have provided below are the files that I have corrected. So you don't need to worry if you want to use them.

Step 4: Order PCB on PCBWay

To make PCB 2 layer PCB with good quality. I use PCBWay services to make a 2 layer PCB for this project. You can see the finished 2 layer PCB in the image above
