1. For industrial control, special or general purpose boards, the bottom circuit is completed, IO is reserved. After purchasing the industrial control board, the reserved input and output ports on the board are connected to the user's own equipment, such as a motor. , solenoid valves, sensors to complete the functions they want to accomplish.
2. A special board is a board designed for a certain function, such as a temperature control board. After purchase, the input port is connected to the thermocouple, the output port is connected to the heating contactor or the solid state relay, and the heating device is controlled to complete the temperature control.
A. Thicken the power cord and ground wire as much as possible
B. As far as possible, the decoupling capacitance is directly connected with VCC
C. When setting the DO file of Specctra, first add the Protect all wires command to Protect the hand-made cloth from being heavily used by the automatic wiring device
D. If there is a mixed power layer, the layer should be defined as Split/mixed Plane, and it should be separated before the line is laid. After the line is laid, the copper should be covered with the Plane Connect of Pour Manager.
