Antminer S19 pro hash board main voltages and measurement method

To learn the maintenance skills of the S19 Pro hash board, we need to master several important voltages, such as the voltage of the level conversion chips, the voltage of the PIC chip, the output voltage of the DC circuit, and the voltage of 5 signals (including cross-domain signals) , the voltage of the LDO chip, etc. This video will focus on the values of these voltages and they should be measured.
