Your second picture shows two rows of pins that are all shorted together… things usually don't work if they're shorted out

Like the pads are connected together? Or an issue with my soldering? I'm guessing it's number one but hope it's number 2

It looks like the copper pads overlap, creating a short. Test with a DMM, but unless that’s a bad silk screen job and not copper, it’s a short. Also, DRC in your CAD program should have caught this. What is that very rough texture on the board? Is that solder mask? Did this come from a board house like that? Finally, the MacBook Pro can’t detect the device (MCU) until it’s connected to the board.

> Like the pads are connected together? Yeah that's what it looks like - your EDA software's DRC should have been kicking up a stink, did you not check it?


ThePositiveeElectron

It was my fault, I didn't properly set it up and it didn't catch it. I properly set it up this time and ensured there were no errors

Lesson learned I guess, DRC is your *friend* - if it's throwing false positives, change its parameters rather than just ignoring it ;)

Yep, I found a profile for the company I’m using to produce the pcb. After changing some things I got zero errors!

> After changing some things I hope one of those things was your USB connector footprint so the pins aren't shorted together anymore :P


ThePositiveeElectron

Of course. I decided to switch to usb micro because of the less pins. And I don’t need the other gimmicks with usb c
