1. Layout Specifications for the WiFi Module Circuit: The layout of the WiFi module should be kept away from the main control CPU and DDRAM and other high-speed digital devices to avoid mutual interference of high-frequency digital signals; The layout area of the WiFi module should include the bottom layer, avoiding the placement of other … Read more
In current microcontrollers, many older models lack Bluetooth module functionality, while new microcontrollers (MCUs) with Bluetooth modules are rarely featured in existing textbooks. Thus, after researching some materials, this article presents a method to add Bluetooth functionality to standard MCU chips, effectively addressing the integration of older microcontroller models with new technologies. 1. The Necessity … Read more

………. Hydraulic component working state characterization parameters mainly include pressure, flow, temperature, vibration, noise, torque, and speed, among which the hydraulic parameters of pressure and flow carry the most system state information. The rapid diagnostic instruments for hydraulic systems are primarily based on the detection of hydraulic parameters for fault diagnosis. The mechanical pressure gauge … Read more
RF (Radio Frequency) and Mixed Signal PCB Layout Guidelines RF (Radio Frequency) and Mixed Signal (Analog & Digital Mixed Signals) PCB design requires special attention to issues such as signal integrity, noise control, and electromagnetic interference (EMI). Their layout differs from ordinary digital PCB design because they involve high-speed signals, the coexistence of sensitive analog … Read more
In the scorching heat, computer cooling fans are indispensable for computers. Whether it is the case’s exhaust and intake, the forced cooling of the CPU/GPU, or the dazzling visual impact, computer cooling fans bear a heavy responsibility. ———————————————- If the host’s cooling is poor, it may cause the computer to lag or freeze. So how … Read more
