This is an open source effort to design and build a Bitcoin mining board based on the second generation Avalon ASIC. The final goal is to have a small board that holds 10 ASIC chips. This board can be controlled via USB communication. An example host would be a PC, Raspberry Pi or TP-Link WR703N router. The host will run cgminer with a custom driver based on the Klondike one and control the board via USB.A 10 chip board should be capable of 15000 MH/s and consume about 30W of power. Alternatively, the switching power supply onboard can be turned to a lower voltage, trading hashrate for power efficiency. The supply is variable from 0.700V to 1.708V. Each board can be easily powered by a low cost power adapter, like this.
