This video will explain the detection method and troubleshooting of the PIC chip on the Antminer S17e hash board. The PIC chip is used to store the operation information of the Antminer S17e hash board, and the control board provides 3.3V powering. If the output of the PIC chip is abnormal, the control board will not be able to communicate with the hash board, which will cause the entire hash board to stop running.
