CPS3 Quick Solder Board for the cps2_digiav

I've been doing a lot of arcade system repairs and mods lately. One quite popular mod is the cps2_digiav by the talented marqs85. This mod gives ditital video and audio output over HDMI for Capcom Systems 1, 2, and 3. The design is quite elegant when installed on the CPS2, but can be a little messy on other systems. A sister board exists to make the install look a bit cleaner on the CPS1, but nothing exists to clean up the install for the CPS3. So I made a thing.

A decided to go with a small antenna connector for BCK, that way it would stay clean and small while keeping the signal clean. On the board itself I kept the BCK signal along the board edge paired with GND.

For the finished product I included a coax antenna cable, a wire harness, the 2 resistors needed for the cps2_digiav board itself, and all additional wires required, pre-cut and tinned.

I think it turned out pretty well, I'm happy with it at least.
Ill throw up Gerber and BOM files on my GitHub.
Premade kits available at my store.
