UPDATE:
Got that switch in the mail today. Managed to rip up one of the traces to it while attempting to clean up the holes. my desolder wick BLOWS, and refused to pick anything up, same with my soldering iron. In any case, I managed to do a really really ugly fix using a random copper wire clipping. It looks like crap but only reads a 0.1 ohm resistance, so without having to redo the entire y1 this is the best I can muster up.
In any case, I also made a jumper cable to connect
J2U pin 1 (VBUS) -> J4D pin 1
J2U pin 2 (VCC) -> J4D pin 2
J2U pin 3 (GND) -> J4D pin 3
J3U pin 1 (GND) -> J5D pin 1
J3U pin 5 (DATA) -> J5D pin 5
It successfully powers the DAC board. The 4.5v test pad reads about 4.3V, all the 5V test pads on the USB board are reading 4.9V. Unfortunately, the 3.3V test pad is only reading 0.5 volts, so thats likely where the problem is.I went through and touched up anything that even remotely looked like a cold joint but I cant get it to work. The light on the bicolor switch remains red and there is no sound from the Y1 standalone. Hope that helps people diagnose what is up.
Also, MisterX, I see you are also in michigan. It lists you as a builder on the Y1 page. Would it be possible for me to give you the y1 for fixing (assuming I cant figure anything out myself) for monetary compensation or do you only build them from scratch?
