I'm waiting for a few informations regarding the 2 chips boards before I can confirm that it'll be a viable miner that's worth manufacturing.
The design isn't fully fixed yet for the voltage regulator. The first board uses a converter with integrated MOSFETs to save some space on board, but the definitive one may use a standard pair of MOSFETs like the old gridseed pods/blades to reduce cost for the end user.
