DON'T buy this crap. i contacted their customer services but they didn't know what is the problem but they only offer to buy a new orage pi card and that other blue card like for 50usd
!!! the original price was like 1800usd but they recently updated their website and now it cost 450usd.
the miner is apparently working since i can scan the miner via baikalscan and advanced ip scanner.
i tried to connect to my pc but it wouldn't recognize. i think it's better that you can use sgminer via your windows command prompt but as you can see on this site forums, it's either not possible or you need advanced knowledge how set this up!
antminer from bitmain could be better since some other windows software supports antminers.
also cryptonight/ cryptonight light coin pool really don't support asic miners!!!
