remember that this *really is* the bare minimum - it'll be amazingly
an under $10 BOM. also that if you _did_ want to add HP and/or TV-out
and/or MIC sockets, as well as OTG.... you can't: there's not enough
room on the connector, not and have MicroSD as well. so you can do 3
out of 4 of those connectors but not all.
