USB interface for configuration and mining communication.
Power supplied through 6-pin ATX PCI-E connector(min 100W ) .
1.3 GH/s guaranteed, 1.6GH/s typical.
85 W power consumption measured at 1.6 GH/s (more measurements pending).
JTAG available for development and debugging (headers are not populated by default).
New features for the  Rev 3:

Heatsink mounting holes, compatible with many heatsinks designed for the Northbridge chipset (59MM).
Additional clearance to allow for larger heatsinks.
3-pin headers to power 8 standard 12V fans.
LEDs to indicate that the FPGAs are configured properly.
Mounting hole size diameter increased to allow for #6 size screws.
238 x 205.5 mm overall size


 
Power:
To power the board, one can use either a standard ATX power supply with a spare 6-pin PCI-E connector. Note that the rev3 board has headers to power 8 fans. If these are used, be sure to include the power consumption of the fans when choosing a suitable power supply.



Software:
The board is currently supported by many software miners: such as CGMINER. Both are open source and publicly available and both work on Windows, Linux, and Mac.

So, $2000 for 1.6GHash? Rip off. You could build a 7970 GPU mining rig for the same hashrate for half the money.

The point of fpga is low power cost for extended use when difficulty rises. 85w for 1.6gh vs about 700w for GPU. Just as I would not recommend making a gpu rig I would not recommend investing in a fpga rig right now. Difficulty is set to double and then triple in the next few months. With a long ROI neither is particularly attractive
