Yes, that is DIP-stix (more or less) One undecided issue is how to 
wrestle with power (3.3V out/in?)
Bread-stix is a prototyping board (multiple holes/footprints) for 
breadboarding.
We are still working on a couple other boards in-house that are taking 
precedence over these so they're not "imminent".
