A Raspberry Pi 4B router is cool, but whats even better is a Raspberry Pi 4 router, with the I/O of your choice, or as I like to say "bring your own interfaces" (BYOI). Well in this video, I take a step up from my Raspberry Pi 4B Router video, and I make a custom Raspberry Pi Router using a Compute Module 4 (CM4), DFRobot's IoT Router Carrier Board Mini, and of course, OpenWrt 21.02.3. With this carrier board, you get two, 1 GB Ethernet NICs, 2 USB C ports (one for power, and one for data), 26 GPIO pins, a microSD card slot, a reset button, and LED indicator lights. This board is already more powerful than a Raspberry Pi 4B router, as it has two ethernet ports, as opposed to one. It has the a small form factor for a low footprint, making it easy for travel. Lastly, you can chose the right CM4 for your resource needs. Overall, this makes a CM4 an ideal system to not only build routers, but anything where you need to customize your interfaces beyond USB, Ethernet, GPIO, and HDMI. Explore the possibilities of a Raspberry Pi CM4, by watching this video to create a router with your choice of interfaces!
