The Dual Gigabit CM4 Carrier Board designed for Raspberry Pi Compute Module 4 is equipped with dual gigabit ethernet ports and dual USB 3.0 ports, making it suitable for soft router applications, while keeping the hardware to a minimum. We have pre-installed a Raspberry Pi Compute Module 4 with 4GB RAM and 32GB eMMC to enable fast boot-up times and a smooth overall experience. You can also replace the installed raspberry pi CM4 with any other CM4 of your choice!
It features a variety of I/O peripherals for more expandability such as MIPI CSI, MIPI DSI, micro-HDMI to connect displays/ cameras, a standard 9-pin USB 3.0 header for more USB expansion, a micro-SD card slot, and an FPC connector while maintaining a compact form factor! This CM4 carried board is ideal for HTPC makers, Linux developers, software router enthusiasts, and the majority of regular Raspberry Pi users.
