Avalonminer A921 hash board repair tutorial
Avalon A921 hash board has a total of 26 ASIC chips. The hash board has the same structure as the A821. Each chip is a voltage domain, and the voltage domains are connected in series. There have domain powering, LDO powering and boost circuit powering. The maintenance of the A921 hash board is mainly to repair the powering and signals. The repair idea is to check the voltages first, and then check the signals. -
Measurement method for Avalonminer A921 hash board powering unit
AvalonMiner A921 hash board power supply unit voltage measurement. This course video explains the specific test points and corresponding voltage values of each power supply unit voltage on the Avalon A921 hash board. For example, the input voltage of the LDO is about 3.5V, the domain voltage is 0.4V, and so on. -
Avalonminer A921 hash board single board report 0 failure
When the tester detects the Avalon 921 hash board, the log shows 0 ASIC chip, how to repair it? First check whether the powering unit is short-circuited, and then whether the voltage of the powering unit and the core powering of the ASIC chip are normal. If all voltages are fine, the next step is to check the CLK signal with an oscilloscope. This video will explain and demonstrate the troubleshooting of the Avalon 921 hash board.
