Apologies in advance for the potato-quality photo, I'll get a better one uploaded when I have a chance. The picture is actually four of the boards as they arrived direct from our manufacturer with a penny for scale. This project was done by the now-defunct Out-of-Plane Labs, a small company I started with a couple of friends with the goal of making cheap hobby-ist electronics. I handled the software; the PCB layout was done by one of the others.
