Raspberry Pi Dual Network Expansion Board

Dual Ethernet Port Expansion: Adds a secondary Ethernet port to your Raspberry Pi, allowing dual-interface networking for routing, gateway, bridge, or firewall applications.

High-Speed Network Performance: Utilizes a USB 3.0 / PCIe-to-Ethernet controller (such as Realtek RTL8153/RTL8152 series) to provide stable 10/100/1000Mbps Gigabit network connectivity with minimal latency.

Integrated Network Status LEDs: Features onboard link and activity LED indicators for both RJ45 ports to easily monitor network traffic, connectivity, and link speed at a glance.

Standard HAT / Stacking Layout: Designed to mount directly on top of compatible Raspberry Pi models via GPIO or USB bridge connections, maintaining a clean and compact footprint.

Wide OS & Driver Support: Recognized natively by Linux kernel distributions and Raspberry Pi OS for simple configuration using standard networking tools (netplan, ifconfig, iproute2).

PCB Composition: Built on a durable multi-layer FR4 fiberglass circuit board with gold-plated RJ45 socket contacts to withstand continuous network connections.

Connector Care: Insert and release RJ45 Ethernet cable latches gently to avoid mechanical stress or damage to the onboard network jacks.

Static Handling Precautions: Standard electrostatic sensitive device (ESD). Handle the expansion board by its outer edges and observe standard grounding procedures during assembly.

Environmental Limits: Operating temperature range is 0^C to 50^C. Protect from high humidity, liquid exposure, and conductive metallic dust while powered.

Ideal for Custom Routers & Gateways: Position as the ultimate hardware module for building custom OpenWrt routers, Pi-hole DNS filters, hardware firewalls, and IoT edge gateways.

Network Segregation Pitch: Highlight its capability to isolate local network traffic (LAN) from external WAN connections or create dedicated IoT device subnets.

Recommended Cross-Sell Add-ons: Pair with Cat6 Shielded Ethernet Cables, MicroSD Cards (pre-loaded or ready for OpenWrt/Linux), and Acrylic or Metal Enclosures.

Universal Pi Compatibility: Highlight compatibility across supported Raspberry Pi mainboards (such as Pi 4B, Compute Module 4 carrier boards, and Pi 3B+).
