First design

[Shahriar sakib]

Sir, I have redesigned the board to my liking.
This is your video : https://youtu.be/po0C5CqseVE
Good or not?

If you are placing a polygon pour, make sure that there are no islands or "antenna's".

That video on youtube is only a small part of the whole course. There are other things to be careful about e.g. try to keep the GND polygon on the bottom side as solid as possible and only use there as few and as short tracks as needed. Also I agree with qdrives.

I see you spent time working on it. Well done!
