Introduction
This dual-Gigabit router carrier board turns a Raspberry Pi Compute Module 4 into a compact foundation for an OpenWrt router, IoT gateway or home networking project. Two Gigabit Ethernet ports combine the CM4's native network interface with a PCIe-connected network controller, keeping both wired connections on one 55x62mm board. A 26-pin GPIO header and USB 2.0 interface extend the build beyond routing to sensors, actuators and compatible peripherals. OpenWrt, Raspberry Pi OS and Ubuntu Server support offer flexibility for network and IoT applications. A Raspberry Pi Compute Module 4 is required and purchased separately.
Dual Gigabit Ethernet with a PCIe Network Interface
This CM4 carrier board provides two wired Gigabit Ethernet connections: ETH1 uses the Compute Module 4's built-in interface, while ETH2 uses a PCI Express 1000BASE-T NIC. This arrangement provides a compact starting point for separating upstream and downstream network connections in a router build. The second network connection uses PCIe rather than a USB Ethernet adapter, leaving the USB 2.0 data interface available for other peripherals. Gigabit port capability describes the interfaces; actual routing throughput depends on the complete system.
OpenWrt Routing with Linux Software Flexibility
This IoT router carrier board supports the provided OpenWrt router system, allowing a CM4-based build to be configured for routing. Compatibility with Raspberry Pi OS, Ubuntu Server and other supported Raspberry Pi systems also opens a path to gateway and home IoT applications. Processing comes from the separately installed CM4 and its BCM2711 quad-core 1.5GHz Cortex-A72 processor. The carrier board supplies networking and expansion interfaces, while the selected operating system and configuration determine the finished system's functions.
55x62mm Form Factor with GPIO and USB Expansion
This compact carrier board retains a 26-pin Raspberry Pi-compatible GPIO header for connecting suitable sensors, actuators and cooling accessories. A USB-C data port provides USB 2.0 High Speed connectivity for compatible storage devices, printers, Wi-Fi adapters or LTE modules, while a separate USB-C port supplies power. The microSD slot supports CM4 modules without eMMC. These interfaces support customized builds in a small footprint, with USB-C 5V/3A power specified for the board.

Fit and function are great with the Milk-V Mars CM Lite and Arace Heatsink 5540A for Radxa CM and Milk-V CM. A small spacer is needed between the DFRobot IoT Router Mini on each corner fastener of the Heatsink 5540A, about the height of two credit cards. The MSEL-DIP nRPIBOOT setting is functional for selecting between the Mars CM Lite boot modes of SPI NOR flash or UART loader; The EEPROM write protect setting does not appear to be useful for the Mars CM Lite, but this is easily accessed by the test pads of that particular module even while mounted on the DFRobot IoT Router Mini. Value for money is good at the $25usd sale price.

I love this carrier board. It's the best one on the market, period. Not even a single issue in 3 months. Up the entire time.
