Expansion board for Raspberry Pi 5 — adds dual 2.5G Ethernet, NVMe storage, USB 3.2 and PCIe connectivity for throughput, professional use. Key benefits performance networking: Two 2.5G Ethernet ports provide stable 2.5 Gbps throughput for lowlatency, bandwidth network traffic. Faster local storage: Builtin NVMe SSD slot and PCIetoUSB3.2 interfaces enable rapid HDD/SSD access and sustained transfers up to 500 MB/s. Reliable continuous operation: Integrated ACT/PWR LEDs plus onboard voltage regulation ensure stable power delivery and clear status indication during extended use. Easy integration: HAT+ design connects directly to the Raspberry Pi 5 GPIO header for plugandplay installation without complex cabling. Expanded I/O: Two USB 3.2 Gen1 ports expose speed peripheral connectivity for external drives, cameras, or USB NICs. What it does and why it matters Consolidates speed networking and storage on a single expansion board, eliminating bottlenecks for dataheavy applications. Offloads storage and network workloads from the Pi's main interfaces via PCIe and USB3.2, improving overall system responsiveness. Builtin power regulation and activity/power LEDs simplify deployment in alwayson or professional environments. Compatibility and form factor HAT+ form factor designed specifically for Raspberry Pi 5 GPIO header integration. Exposes two USB 3.2 Gen1 ports and a single NVMe slot via PCIe connectivity while adding two 2.5G Ethernet ports. Power and status LEDs (ACT/PWR) and voltage regulation circuitry are included onboard to match professional hardware requirements. Typical applications 4K video streaming server: Use the dual 2.5G Ethernet and NVMe storage to stream bitrate 4K content from a compact Raspberry Pi 5based server. NAS / file server: Build a small, performance NAS with direct NVMe storage and multigig Ethernet for fast file transfers and backups. Industrial automation or edge compute: Add reliable multigig networking, fast local storage, and realtime status indicators for factory floor or edge deployments.
