This project contains a circuit board, firmware and cgminer/bfgminer patch to get the new Avalon Gen2 ASICs (A3255Q48) hashing.

Board features:

• Very efficient (~90%) DC/DC converter to power the ASICs
• Adjustable voltage (0.85 - 1.25 V) to choose between efficiency and overclocking
• USB-Interface to connect to a host running cgminer or bfgminer
• TWI interface to chain multiple boards together
• 100% flat surface on the bottom side to mount a usual heatsink
• On-board temperature management
• Fan connector with rotation speed measurement and PWM-control
• Indicator LED to report USB-activity
• 4-layer PCB for optimal heat/current transportation
• Two board designs available: one for 10 and another for 16 ASICs

cgminer/bfgminer patch features:

• Reporting temperature, real ASIC frequency and fan-speed back to the host
• Control of ASIC frequency in a big range from 62.5 to 5000 MHz in smallest possible steps
• Control of a desired temperature
