Schematics

Hi ravpreet420

Here is it!
I suggest you to study all the schematics and post your doubts here before start doing something.
Remember, a mistake solved in paper cost 10x less than a pratical mistake!:D

Good luck!

Very nice project and very well executed! I am really impressed with the level of performance you achieved for a home-DIY project! Thank you also for sharing the details and documentation!

How did you design the PCB and schematics? What was the CAD program?

Wow, nice work! Thank you!
