I've missed this direct from the team type of information. Looking forward to seeing the new design in action.

Did Canaan move away from the Rasp Pi for a controller? I don't recall where but there was someone here talking about a different controller model. Not sure if it was just a regional thing or not. Two different options regarding the PSU's is great, I had resigned myself to having to get models with a built in. Say you buy option 1 and the PSU dies, is it easily converted to accept a regular PSU moving forward? Or would someone need to order a replacement from Canaan?
