After a brief flirtation with using a flattened out DIP8 ATtiny85 (there should be a Hackaday post about this) that I'm calling the 1.x series, I've now got PCBs for the new 2.x version of the SAO in hand.

I'm overall very happy with these, but even still, I've already made a version 2.1 and sent that out for (final) fabrication. The main changes are a slight adjustment to the vertical position of the screen cut-out, and a solder jumper that will enable/disable the UPDI pin in the SAO header. In testing, I found that at least one badge with a 6-pin SAO header freaked out when the deck was plugged into it, so to stay on the safe side, I'm going to have a way for folks to easily disconnect the programming pin.

That said, 2.0 is good enough for distribution, and I'll be building at least a few of them. So if you're reading this post-Supercon and have one of these boards, you've got a pretty rare piece of kit. Just, you know, be careful about using it with 6-pin SAO badges...
