I've been working on this for a while, but waited forever to get the PCBs made. Finally did, and also got the parts, and started soldering

There are a few SMD components which I put on first. Really have to get a new soldering iron, and practice my SMD soldering skills more.

All parts necessary for some initial testing in place. But turns out I couldn't flash it using the ISP connector, because the ground planes weren't connected properly.

The problem and the fix. Quite simple to fix in the next revision, but I should've totally seen that. And all the sudden, the ISP works as well.
