is this the same board as it was advertised here?

or this this a new design? it does not tell which board or design is used on bitfurystrikesback.com

No, it's not the same board. Look at the pictures:

The right side of the board with the 16 ASICs is virtually identical, but the left side is different. On the H-CARD from bitfurystrikesback.com, you see that the left side is much simpler. It only has the power regulator for the chip core voltage and the edge connector.

On my S-HASH board, the left side contains a different power regulator (50A instead of 30A), and a CPU with Ethernet interface. Functionally, they are different too. The H-CARD on bitfurystrikesback.com plugs into an M-BOARD, and the M-BOARD hooks up to a Raspberry Pi computer board with the miner code.

My S-HASH board works stand-alone. You don't need any other boards, no Raspberry Pi. Just hook it up to 12V power supply, plug the ethernet cable in your internet router, configure it for a mining pool, and start making coins.

Of course, the S-HASH board will be more costly to produce than a bitfurystrikesback H-CARD, simply because it has more components and a more expensive power regulator. Of course, when you add the M-BOARD and the Raspberry PI, the S-HASH board will be cheaper to produce. But if you need more hashing power, and stick in additional H-CARDs, the bitfurystrikesback system will win again. So, it all depends on what people need.

The other difference is that the H-CARD runs at a lower core voltage, and will be more power efficient. So, for large applications where electricity is an important part of the cost, that may turn out to be a better choice. For small home miners, the cost of purchase will be more important, and power consumption/heat generation will be secondary. In that case, running the chips faster will get more coins for your coins.
