I wasn't happy with the parts I'd used in Eagle and the resulting silkscreen, so I updated the board... which meant having to rearrange things. So that's v3. I also added some indicator LEDs to a v4 board with SMD parts; I'm keeping v3 and v4 separate so as to keep the option of not doing SMD open.

Something that I've been thinking about is whether the copper trace widths I used (10 mil) is enough for the power I want to pull. I think the traces are short enough that it's fine, but think v5 is going to feature wider traces.
