BTCMiner is a Bitcoin Miner software which allows you to make money with your ZTEX USB-FPGA Module. Since these FPGA Boards contain an USB interface no additional hardware (like JTAG programmer) is required and low cost FPGA-clusters can be build using standard USB hubs.



  • Supported FPGA Boards:
  • Dynamic frequency scaling / overclocking based on error measurement, i.e. BTCMiner automatically chooses the frequency with the highest rate of valid hashes.
  • Cluster mode: one software instance can control many FPGA Boards (up to several hundreds, limited by the number of USB host controllers)
  • Hot-plugging: new FPGA Boards can be added / removed during runtime
  • Stale reduction by Long Polling and block monitoring
  • Backup server / pools
  • Possibility of enumeration of FPGA Boards and cluster partitioning using that numbers
  • Power save mode after 5min inactivity of per command
  • Temperature monitoring and overheat shutdown (USB-FPGA Module 1.15y rev. 2)
  • Overheat protection by shutdown if error rate increase to much
  • Logging
  • Package is Open Source
  • Ready-to-use Bitstream, i.e. no Xilinx Software or Licence required
