Rev 0.2 is fine for half baked or quarter baked.  Let's call the yardboard rev 0.2 after the wireball rev 0.1.
I'll plan on getting you the rev 0.9, not the yardboard.

I'd love help on code.  I think we'll maybe get some code working to record zaps before too long:-)

micropython comes with a ready made file system and can write on SD cards...

Probably anywhere in the continental US is good.

More test waveforms coming in a few minutes.
