Bitmine A1 Chips

Today I received two Bitmine A1 sample chips. Now we only need a design for a PCB 🙂 Or maybe setup something with The Wasp Project Collective. Anyway I have great plans in mind.

Update April 12th: Plans have changed, I am not going to use the A1 in a project.
These two A1 chips are for SALE for only 0.17 BTC which includes free worldwide shipping.
Update June 20th: Chips are SOLD
