How to measure the voltages on the Antminer L7 hash board?

Every voltage is normal, which is the basis for the operation of the hash board. Therefore, this video mainly explains the measurement points of important voltages on the L7 hash board, as well as their specific voltage values. Such as the domain voltage, the voltage of 5 signals, the voltage of the cross-domain signal, and the voltage of the LDO chip of the last 4 domains and other domains. When repairing the L7 hash board, the first thing to do is to ensure that the voltages are normal.
