What is the PIC chip on the Bitmain S19 hashboard? How do PIC chips work?
The PIC chip is used to store the computing frequency and related operating voltage information of the Antminer S19 hash board, and to control the communication between the DC circuit and the control board. The voltages of pin 1, pin 2, pin 9 and pin 10 of the PIC chip are all 3.3V. If the log shows that the PIC is faulty, you need to check the voltage of these pins first.
