Title: Please, I need help designing my PCB board.
Post by: amin08 on October 30, 2017, 11:56:31 pm
Hi!
Recently I've been designing my final project PCB, and as you may know, I'm not a professional electronics designer  :-//. I would like someone to help me review the board(schematic and design) before sending it to manufacture.
It's the only step left before finishing the project |O

Ok, so let's see it.

Ok, so the first part of the circuit is the power supply, basically, it's a power source switching circuit that changes from USB to DC(If USB is plugged in and we plug DC jack, USB is cut off). There's also a switch that selects between 10.8V battery and DC jack.
Please, any advice or help is appreciated

Thank you ;)

Can you actually make a readable picture?

You might be best uploading the EAGLE schematic file itself, and/or a PDF export (for those that dont use EAGLE), rather than images of different pieces of the circuit. People will be able to help more effectively if you do this.

The Arduino UNO R3 has a similar circuit to switch from USB to DC jack:
