The RK3588 core board is a widely used 8K flagship SoC chip from Rockchip, and it is one of the domestic chips frequently used by many electronic engineers. When using the RK3588, EMC issues often arise. So, how can we reduce these EMC problems? 1. Mold Isolation Design Connectors should be recessed as much as … Read more
In RS485 communication systems, the choice of grounding method is crucial, directly affecting the system’s stability and anti-interference capability. Therefore, engineers need to choose the grounding method reasonably based on project requirements. Below we will discuss which grounding is suitable for the RS485 bus. 1. Single Point Reliable Grounding There can only be one grounding … Read more
Introduction: The RS-485 bus is now used less frequently, but many systems still rely on it, making it necessary to learn about it. Main Content: 1. On-site Wiring Specifications The RS-485 bus is widely used due to its low cost and simple design, finding applications in security monitoring, intelligent transportation, smart buildings, data center monitoring, … Read more
Basic Principles of Data Transmission Technology 1. Characteristic Impedance and Delay Characteristics Ideally, due to the in-phase relationship between the voltage and current of the resistive components, the input signal experiences no phase shift when passing through the resistive network, only inherent attenuation. In practical circuits, since cables do not possess purely resistive characteristics but … Read more
