recently i found this fpga-board, optimized for cryptocraphic calculations.
it only requires a power source and a usb-cable, no jtag required. you get mining software and firmware for the fpga for free, hashrate is described at typical 190 MHs/s.
power consumption is 8 watt. one con seems to be the price, which is at almost 400€.
has anyone in this forum experiences with this board?
This rather vague... There are multiple fpga-boards, which did you find?
