While I'm appreciative of the new level of communication, it is now clear that BA has bitten off WAY more than they can chew. Redesigning a control board when a RasPi and BeagleBone Black are readily available? How will this help you deliver more quickly?
Refund requested from Minersource. Fingers crossed.
Embedding the equivalent of a Raspberry Pi into your own hardware is not a big deal any more. It hasn't been for some time, only now it's a whole lot cheaper thanks to the introduction, and success of the Pi. The extra effort just goes to show BA are in this for the long haul.
