ZTEX FPGA Boards for Bitcoin Mining
ZTEX is a manufacturer of FPGA boards. ZTEX offers USB-FPGA Modules 1.15y with four Spartan 6 LX150 and USB-FPGA Modules 1.15x with a single Spartan 6 LX150 which are optimized for cryptographic computations like Bitcoin Mining.
These FPGA Board have on-board voltage regulators and an USB controller which is used for communication and device programming. Low cost FPGA mining rigs can be build using standard components (USB hubs, USB cables, ATX PSU's).
With the current version of the BTCMiner an average hash rate of about 215 MH/s per FPGA can be achieved. Power dissipation is 9.8 W at 216 MHz.
Current prices including volume prices are stated at the Bitcoin Forum.
