Hey guys,
Just so you know, I received my miners 3 days ago, and have been trying to hash ever since. I think it may be a backplane PCB board issue, or a power issue. I doubt its the raspberry pi board or the Serial cable board underneath.
They do hash, and they are legit.
I may have a power issue, not allowing me to run more than 2 boards/3boards at a time. Also, I don't trust the backplane design into ARM but that's personal preference... But they are real miners...Heres my ghetto RIG setup.

I'm opting for two power supplies to draw off two different circuits so I don't trip a breaker. luckily I have a floor plan that makes it really easy to go that route, then I'll get a 1500 watt later when I get a few ant miner S1 and use the current power supplies I have for those.
