Step 1: SOLDERING THE COMPONENTS TO BOARD
I have hand soldered all the components using a soldering gun which was sourced locally. Hand Soldering of SMD components is a bit tricky which can be done only on prototype boards. For production machine soldering is recommended.
Step 2: ASSEMBLED BOARD
In the above images, you can see the final assembled board.
Step 3: TESTING OF ASSEMBLED BOARD
Just connect the assembled board to any USB port on the laptop.
Measure the voltage between the points marked in yellow as shown below using a multimer.
The multimeter shows 12 v reading between those points.
This module is portable and can be used in a variety of applications.
