Description:

Empower your IoT and networking solutions with the Raspberry Pi Compute Module 4 IoT Router Carrier Board Mini. This compact yet robust internet expansion board is specifically designed for the Raspberry Pi Compute Module 4, transforming it into a high-performance router and versatile IoT gateway. Leveraging a direct PCIe interface for its dual full-speed Gigabit Ethernet ports, this carrier board delivers superior network throughput, reduced CPU overhead, and enhanced long-term stability compared to USB-based network solutions. Despite its miniature 55x62mm footprint, it retains the familiar and highly adaptable Raspberry Pi GPIO header, enabling seamless integration with a wide array of actuators, sensors, and intelligent cooling systems.

A convenient USB 2.0 port further expands its capabilities, allowing connectivity for external storage (mini-NAS), printers, Wi-Fi and LTE modules, and other peripherals. Pre-loaded with the open-source OpenWRT router system for easy setup, it also boasts compatibility with Raspberry Pi OS, Ubuntu Server, and other Raspberry Pi operating systems. The powerful quad-core BCM2711 processor and extensive software support from the Raspberry Pi community provide a solid foundation for building advanced gateways, smart routers, and comprehensive home IoT platforms. Its versatility extends to applications as a mini-NAS, wireless network bridge, or LTE-enabled internet terminal.

Important Note: The CM4 board socket is delicate; ensure correct alignment before gently pressing down. Repeated plugging and unplugging of the CM4 module is not recommended. Always verify the CM4 installation direction before powering on.
