-
There are two boost circuits on the Antminer S19 hash board. This video mainly explains the 21V boost circuit. How do 21 volts work? What is its maintenance idea? The 21V boost circuit on the back of the S19 hash board is mainly used to turn on the 4 MOS tubes on the front. If these 4 MOS tubes cannot work normally, there may be an abnormality in the 21V boost circuit.
