The main conductor material used in PCBs is copper foil, which is used for transmitting signals and currents. At the same time, the copper foil on the PCB can also serve as a reference plane to control the impedance of transmission lines or as a shielding layer to suppress electromagnetic interference (EMI). Additionally, during the … Read more
Embedded software may experience coupling between drivers and applications due to hardware resource limitations. However, for large projects with ample resources, complex business logic and the need for future expansion and maintenance necessitate the adoption of layered and modular thinking, which is the essence of architectural patterns. Common architectural patterns available in the market include … Read more
