Allstar/DVSwitch PTT Board with Pi CM4

Introducing our innovative modular, AI-powered DIY laptop carrier board project! This design focuses on a step-by-step approach, starting with a solid architectural scaffold that lays the groundwork for a high-performance system. The project is built around a hierarchical schematic structure including: • A Top Sheet outlining the system overview and power tree • SoM Connectors organized into three 100-pin assemblies (two CM4/5-compatible and one dedicated to high-speed operation) • Dedicated Power/PD management • An M.2 A+E interface for the Coral TPU (PCIe x1 from PORT0) • An M.2 M-key interface for an NVMe SSD (PCIe x2 from PORT1) • Comprehensive USB & Hub configurations • A microSD integration module • Supervisory and Reset controls The design aligns with cost-effective 4-layer board stackup practices (JLCPCB friendly) while following best high-speed design guidelines for USB/PCIe integrity. The integrated silkscreen placeholders feature custom sci-fi fonts for a unique, personal branding touch. Key routing notes include precise PCIe lane mappings based on the Orange Pi CM5 manual, ensuring clean ground return paths, effective decoupling, and proper AC-coupling placement. With paired USB hubs optimized for minimal depth and latency and robust power sequencing strategies, this project is poised to evolve into a high-speed, scalable prototype. #DIYElectronics #ModularDesign #PCBDesign #EmbeddedSystems #PCIe #USBDesign #OrangePiCM5 #TechInnovation #HighSpeedElectronics
