Universal Jamma Adapter Board + Extension Boards

[DeWitt]

Hello everyone,

I'm currently working on a universal JAMMA adapter board which I can use to build rapid prototypes instead of designing multiple adapters for my needs. I started doing that and it got really time consuming...

So here is my current progress:


JAMMA adapter mainboard

The extension boards are designed to fit on top of the "mainboard":


Small extension board


Big extension board

The holes that connect bottom and top need to have exactly this spacing. I have an audio amp that fits exactly.

All my work is based on a design of @Frank_fjs (Jamma Fingerboards) and my gerber files will be free to use when I'm finished.

Feedback is highly welcome

PS: please be gentle. Its my second time that I used a PCB software...

Thank you very much for your kind words!

It is actually true it was the second time, it took me forever! I posed my first PCB in @Frank_fjs Jamma Fingerboards thread.

I really need to work on understanding this software better! I did a lot of copy & paste. Positioning and spacing was done by hand and not really exact. There should be tool support, I haven’t found it. I also switched between mm and inch while editing, this messed up a lot of spacing. But in the end I’m happy with the result!

My superpower is patience, that’s all, no magic!
