Description Deploying YOLOv8 on Wildfire RK3588, we use yolov8s.pt (downloaded from the YOLOv8 official website) as an example. 1. pt->onnx Do not use the official YOLOv8 code; instead, use the Rockchip YOLOv8 code, available at https://github.com/airockchip/ultralytics_yolov8 After downloading the code, execute the model conversion with the following code: from ultralytics import YOLO model = YOLO('yolov8s.pt') … Read more
On Friday,PCB prices for some stocks have already reached new highs, while others are approaching their previous highs. During the downturn, it was believed that AI capital expenditure growth had peaked, and domestic CSP manufacturers had money but couldn’t spend it. During the upturn, it was thought that if US stocks in AI could reach … Read more
A common high-speed PCB design rule is to track the return current path of signals. In reality, this is much easier said than done, as the return paths for fast digital signals and even medium-frequency analog signals are largely confined beneath the traces. At very low frequencies or under direct current (DC), the return path … Read more
Introduction This article uses a synchronous step-down converter power IC in an SOP-8 package as an example to introduce the PCB design for power supplies. Related Parameters As mentioned in “Guidelines for PCB Design of DC/DC Switching Power Supplies: Part One”, it is essential to understand the related parameters before starting the design, as shown … Read more
PCBEngineers often find multilayer circuit boards confusing at first glance, especially with layers reaching ten or more, resembling a spider web.Below are several internal structure diagrams of multilayer PCBs, showcasing various stacking structures in a three-dimensional format. 01 The core of High-Density Interconnect (HDI) boards lies in the vias. The processing of multilayer PCB traces … Read more
