DFRobot CM4 Router Carrier Board Mini

Description

The DFRobot Compute Module 4 IoT Router Carrier Board Mini serves as a robust internet expansion solution for the Raspberry Pi CM4. By leveraging the CM4’s PCIe interface, this carrier board provides two full-speed Gigabit Ethernet ports, delivering significantly improved network throughput, lower CPU utilization, and enhanced long-term operational stability compared to USB-based network adapters. Its miniature footprint of 55x62mm is ideal for embedded applications, yet it thoughtfully preserves the essential Raspberry Pi GPIO pin header, allowing seamless integration with sensors, actuators, and smart cooling solutions.

Beyond its core routing capabilities, the board includes a convenient USB 2.0 interface, enabling connection to external storage drives, printers, Wi-Fi modules, or LTE modems for diverse application scenarios. Pre-configured with OpenWRT, it can function as a powerful, customizable router out-of-the-box, while also supporting standard Raspberry Pi OS, Ubuntu Server, and other CM4-compatible operating systems. Powered by the CM4’s BCM2711 quad-core 1.5GHz Cortex-A72 processor, this carrier board provides a solid foundation for developing high-performance network gateways, smart home IoT platforms, mini-NAS devices, or wireless network bridges.
