Read clock: They use another pin for that with this one too. 2. Found another function very early one that does this: Clock out hex 01, wait a while and then clock out an insane amount of zeroes. These two correspond to "software reset" and "nop" respectively for several of their controllers cog size: ~15 x ~3 mm

It looks a lil funky
