Anyhow, the Gerber files are below and will also upload design files shortly.
Who designed this and made Gerber files, you or someone made this for you?
It looks very cool and you even added your own bitcointalk username on PCB, nice touch Wink
Myself! Yeah, wouldn't have added it if someone else made it of course. Tongue
Actually I found a footprint of the ASIC on the EasyEDA web editor - who knows, maybe they also created the Antminer S9 in EasyEDA!

I will continue to work on this project, so if anyone wants to chime in and / or help in this project (for example working on the power supply), don’t hesitate to comment or DM me! Any suggestions are welcome.
I am afraid that I am not even nearly enough skilled to help with power supply or asic miners, and I can only work basic electronic fixing, soldering, etc.
Maybe you should try contacting guy who is working on Computer Module 4 raspberry pi devices, for running bitcoin nodes.
He is called Mirek and you can also find him by the name MirkoPC.
On this forum? I believe the biggest help would be someone experienced with power electronics giving advice for a good buck converter that takes 5V, 3A (such as from a GekkoScience USB hub) and spits out a nice clean 0.4V with dozens of amps available. But it may not even be required for now. I suspect the chips don't start hashing and pulling enormous amounts of power if you don't instruct them to.

This repair guide with its 'signal description' chart should come in very handy during reverse engineering.
