Basic Information

    3.5T (+-5%)

Power consumption:
    990W (measure on 12V port of the device)
    1100W (on the wall, with assumption of 90% power conversion ratio)

Power per hash:
    270J/THash (device only)
    295J/THash (on the wall, with assumption of 90% power conversion

    Support automatically optimize frequency, no need to overclock manually.

PSU output pin:
    4x6PIN PCIe power connector. *All must be connected.*

PSU requirements:
    Minimum 1100W output, recommend to use high-quality PSU for server
with more than 1200W output and high quality power cable.
    Input voltage no lower than 11.7V and no higher than 12.2V (numbers
take from the controller)
    Lower voltage leads to lower hashrate and higher voltage leads to
possible device burning down.
    NOTICE: Poor quality cable may result in low voltage.

    Specs: 12038
    Current: between 1.6A and 2.8A.
    Minimum RPM: 3800.
    *NOTICE* If the fan is broken or the fan's RPM cannot be measure,
the device will not start.

    Raspberry Pi (version B or B+)
    Raspberry Pi 2 will be supported at the middle of December 2015
    Each Rpi can control approximately ~12 devices.

    Each AUC can connect up to 6 devices.


Net weight:

Protection Degree:


White Power on
Blue Working normally
Yellow blinking Idle normally
Green blinking Detect fan and mcu
White blinking Turn on LED manually
Red blinking Toohot/Loopback failed/PG failed/Coretest failed/Voltage error/Temperature sensor error/No fan

MM Error Codes

Query EC here

1 CODE_IDLE WARN Idle Check if the network is ok or AUC is work normally
2 CODE_TOOHOT FATAL Too hot Check if the fan is connect successfully
4 CODE_LOOP0FAILED FATAL Channel 0 loopback failed Replace a new hash unit for channel 0 if PG0 is ok

16 CODE_INVALIDMCU FATAL MCU cann't be detected Replace a new CTRL board
32 CODE_NOSTRATUM WARN No stratum Check if the network is ok or AUC is work normally
64 CODE_RBOVERFLOW WARN Nonce ringbuffer overflow Ignore it please, If CGMiner is restart, It will be ok.
128 CODE_MMCRCFAILED WARN Ignore it please, If CGMiner is restart, It will be ok. Find iic rx crc mismatch
256 CODE_MCUCRCFAILED WARN Find mcu rx irc mismatch Ignore it please, If CGMiner is restart, It will be ok.
512 CODE_NOFAN FATAL Fan cann't be found Check the fan connection
1024 CODE_PG0FAILED FATAL Channel 0 power good failed Check the PSU for channel 0
2048 CODE_PG1FAILED FATAL Channel 1 power good failed Check the PSU for channel 1
4096 CODE_CORETESTFAILED FATAL Find bad chip on channel 0 or channel 1 Replace a new hash unit if hash rate is too low, or else you can ignore it.
8192 CODE_ADC0_ERR FATAL Temperature sensor cann't be detected on channel 0 Replace a new hash unit for channel 0
16384 CODE_ADC1_ERR FATAL Temperature sensor cann't be detected on channel 1 Replace a new hash unit for channel 1
32768 CODE_VOL_ERR FATAL MM is not permit to run at the voltage for safety Change another PSU for the machine

TYPE meaning:

 WARN-It designates potentially harmful situations, but you can ignore it.
 FATAL-It designates very severe error events that will presumably lead the Avalon6 to crash.

    3. DFU Functional Descriptor
    4. DFU Mode Interface Descriptor
  3. Detail USB-DUF Product's USB Descriptor

cd dfu-util
The resulting binary is dfu-util/src/dfu-util.



  1. Support Raspberry Pi 2B
  2. Update with the master branch
  3. Support Avalon6 in LuCI (Advanced version)
  4. Keep more coding on LuCI (Avalon theme)


  1. Add auto speed option
  2. Merge the Avalon6 code to CK's master


Known Issues

  1. MM can be upgrade by mismatch firmware.
  2. local hashrate (GHS av) cann't match with the pool's hashrate
  3. Use 5 or more modules in one AUC will cause MM idle periodically.
  4. Duplicate MM address


1. How to deal with the red blinking machine?
