Did some more PCB layout stuff. Changed the processor over to a TSSOP (it seems to fit a bit better). Wrapped up routing after some more schematic modifications. Rounded the corners. Putzed about with the power section a wee bit so all the components (other than the battery) are on one side. Fattened up the GND and VCC rails to a monstrous 0.5mm. Still need some way to program the silly thing; might be a good excuse for a DIY pogo jig of some kind (you can see the Tag Connect footprint on the left--it's a bit too big, and the cables are spendy).

Definitely needs to be gone through a few times before sending off to OSH.
