Those power and Mhash/s claims are a little outrageous. Be wary about this one until we have some better data

Maybe the power consumption #'s could be caused if ztex only measured the core power usage. The 6.8W number from our FPGA board was the total power usage of the board- including fan and regulator inefficiencies.

EDIT- and just after I post this, he changes the power #'s!! Fishy. From 2.8 to 5.9W on the LX150

Can you ship internationally? This is awesome for us with high electricity bills.

The power requirements can't be. You don't just get 200%+ more efficient with another board design or different hdl code.

I measured it on Friday: 310mA @ 11.7V. 

In order to go sure, I'll measure it with a different device.

Have you proof of these numbers? The power requirements can't be.

For amounts of 100 or larger a license production program can be offered which allow to build large clusters at competitive prices in comparison to GPUs.

whoa.

BTCMiner -- Bitcoin Miner for ZTEX FPGA Boards,  215 MH/s on LX150

BTCMiner runs on Linux and Windows and supports USB-FPGA Modules 1.15b and 1.15d, USB-FPGA Modules 1.15x and USB-FPGA Modules 1.15y. These FPGA Boards contain an USB controller which is used for data transfers and device programming. Thus, no additional hardware like JTAG adapters is required and low cost mining clusters can be build using standard USB hubs.

BTCMiner supports dynamic overclocking based on error measurement, i.e. the software scales the frequency such that a maximum rate of valid hashes is generated.
A cluster mode with hot-plugging support allows to run large mining rigs from one software instance.

For complete list of Features please visit the BTCMiner Homepage.

For bitcoin mining I recommend the USB-FPGA-Module 1.15x (1 x XC6SLX150) or USB-FPGA-Module 1.15y (4 x XC6SLX150) which are optimized for such purposes.

Prices (including volume prices) can be found in the hardware thread: https://bitcointalksearch.org/topic/ztex-usb-fpga-modules-115x-and-115y-215-and-860-mhs-fpga-boards-49180


USB-FPGA Module 1.15x with cooler.
