reRouter CM4 1432 - Raspberry Pi Based Mini Router, Travel Router, Dual Gigabit Ethernet, OpenWRT OS

Is your router secure? Buy a router or build a router? Want to set up a VPN client, or block all ads? Then you might want to build a router rather than buy a router. We highly recommend setting up a DIY Raspberry Pi router with OpenWRT, however, it always brings some trouble when you configure a new system. So we pre-installed an out-of-box and secure Raspberry Pi router for you!

This Mini Router 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.

Features

• Fast boot times and smooth overall experience: Powered by Raspberry Pi Compute Module 4 and 4GB RAM/32GB eMMC
• Compact and highly integrated: 75x64x21mm in size, with dual Gigabit Ethernet ports and dual USB3.0 ports
• Highly scalable with rich IO peripherals: dual Gigabit Ethernet connectors, Micro-SD card slot, micro-HDMI interface, USB 3.0, MIPI CSI, MIPI DSI, etc.
• Easy to deploy with stability: DIN rail mount and keyhole slot allow you to hang it anywhere
• Pre-installed OpenWRT firmware: Out of the box, can easily implement software router applications

OpenWRT Pre-Installed

The Compute Module 4 comes with OpenWrt firmware pre-installed out-of-the-box. This means you just need to unbox the package, take out the board, connect to your existing home network and have your own mini router!

OpenWrt is an open-source Linux operating system which 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

Why choose Raspberry Pi 4 for the home router？

1. Increase Network Bandwidth and Performance

While the Raspberry Pi is definitely weaker in comparison to a full-fledged desktop or laptop, its Broadcom CPU is certainly more than enough when it comes to network routing. Thus, a Raspberry Pi router will surely be a boost to your network and give you greater internet speeds!

2. Improve Network Security
With a Raspberry Pi Router, you’ll be able to choose from free, open-source operating systems like OpenWrt that are community reviewed and maintained for security!

3. Enjoy Additional Features
With the accompanying hardware and I/O, using a Raspberry Pi as a router grants you flexibility in adding more features.

What kind of OS a router can run?

So what kind of OS can these special routers run? Windows, Mac? Of course not. A router does not need to run this kind of heavy OS because it would not make sense. So, there are some special operating systems that are specifically designed to run on this type of router, and most are Linux-based. These operating systems are much lightweight allowing them to be run on low-end CPUs and low RAM available on these routers. Also, most of these operating systems are open-source, which means you do not need to pay extra to have access to them.

If you want to learn in-depth about these router OS, you can visit this blog. Some of the most common router operating systems are:

• OpenWrt
• pfSense
• DDWRT
• OPNSense
• ClearOS
• IPFire

Out of the two Gigabit Ethernet Ports (RJ45), one Ethernet Port is connected to the Gigabit Ethernet PHY of the CM4 module which is based on Broadcom BCM54210PE. On the other hand, the other Gigabit Ethernet Port is connected to Microchip's LAN7800 which is a USB 3.0 to GbE (Gigabit Ethernet Bridge). The USB 3.0 interface here is extended from the PCIe interface of the CM4 Module. Also, both ports can support speeds up to 1Gbps.

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, 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.

Also, this comes included with a PC/ABS case with an Aluminum alloy on top which has a large sink in order to cool down the CM4 at extreme loads. It provides better protection as well and is suitable to be used in industrial applications.

Heat Maps

The case has long rubber feet for better stability when placed on a flat surface. You can mount this case in two different methods. One is to use the keyhole slot wall mount and hang it on the wall (you can hang in 2 different orientations). The other is to use the 3 mounting holes and mount onto a DIN rail.
