Compute Module 4 is officially launched on 19th October 2020 with the same or better spec, and there are 32 variants of the module to choose from. This product page lists Compute Module 4 which comes WITH Wireless (WiFi and Bluetooth), 2GB RAM, and NO onboard eMMC (Lite).

Dual Gigabit Ethernet Carrier Board for CM4

The Dual Gigabit Carrier Board designed for Raspberry Pi Compute Module 4 is equipped with dual Gigabit Ethernet ports and dual USB3.0 ports, making it suitable for soft router applications, while keeping the hardware to minimal.

It features a variety of I/O peripherals such as MIPI CSI, MIPI DSI, micro-HDMI to connect displays/ cameras, a standard 9-pin USB 3.0 header for more USB expansion, and a micro-SD card slot, and an FPC connector while maintaining a compact form factor! This board is ideal for HTPC makers, Linux developers, software router enthusiasts, and the majority of regular Raspberry Pi users.

OpenWrt Supported

You can flash OpenWrt firmware after attaching a Compute Module 4 to this board and turn this board into a software router!

OpenWrt is an open-source Linux operating system that runs on embedded devices/ routers. It offers more features, performance, and security than a traditional router. It has a filesystem that’s fully writable and includes a package management system. You can make use of these packages to suit your applications in various ways. Once you connect this board to your home network and access the router from a web browser, you will be presented with a beautiful and interactive dashboard as follows.

You can navigate this dashboard, and you will have access to a bunch of features such as:

• Increase overall network performance when multiple devices are connected
• Share files between devices via an external storage drive connected directly to the router
• Increase network security
• Run a BitTorrent client from the router
• Connect a printer directly to the router to create a networked printer
• Limit bandwidth usage of a particular device in the network
• Active queue management
• Real-time network monitoring
• Create Dynamic DNS
• Set Up a VPN client or server
• Block ads on the network

By utilizing the above features, you will have unlimited possibilities with this mini router!

To get more understanding of how the router works (using the CM4 with this Dual Gigabit Ethernet Carrier Board) and more details explanations about this carrier board, you can watch this great video from Gary Explains.

Applications:

• Software Router
• IoT
• Smart Home
• Camera Projects

Since the CM4 Lite does not come with onboard eMMC, it will need an external microSD card that has a compatible OS image to boot up. So 1st thing after you get the Dual Gigabit Ethernet Carrier board and a proper power supply, you will need a microSD card (at least 8GB) with a suitable OS image in it. We have included the Raspberry Pi Approved MakerDisk 32GB microSD card and a USB microSD card reader/writer. You can use it to write the OpenWRT image into the microSD card.

A tiny and useful USB MicroSD Card Reader/Writer is included
