A circuit, the route through which current flows, is composed of components such as a power source, a load, connecting wires, and switches. The same is true for the circuit of the hash board or the control board. Only the circuit of the whole board is not abnormal, the hash board or the control board can operate normally. Therefore, it is crucial to recognize and master the basics of circuits.
