Firmware

703n/RPi Host Firmware

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

 https://en.bitcoin.it/wiki/Avalon2#Firmware

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
