Firmware

703n/RPi Host Firmware

After 20140320, the Avalon2 firmware support both Avalon2 and Avalon3 out of box. Please download the firmware here:

2014-04-01

  • MM Version: 331404-ed2bbc80
  • When temp > 90C. MM will power off all ASICs
  • Make the Avalon3 MM 100% compatible with Cgminer Avalon2 code
  • Please use the Avalon2 703n/RPi firmware after 2014-03-20. the firmware will support both Avalon2(A3255) and Avalon3(A3233). PLEASE NOTICE
    • The voltage range is different
    • Voltage: 0.6v ~ 0.8v
    • The frequency is Mhz not MHs under Avalon3. so the range is
    • Frequency: 400MHz ~ 650Mhz (MHz * 11.81 = MHs)
    • For example: if you config the Frequency to 400 under Avalon3 that mean 400 * 11.81 = ~4.7GHs

NEXT-TESTING

  • NOTICE: Only for testing

Design file

You can put 7 or 10 chips per small miner.

7 chips: high hashrate with more power consume
10 chips: high hashrate with more ASICs. save more power
