YouTuber Jeff Geerling has expanded on his Raspberry Pi Compute Module 4 teardown and introduction videos and has provided an overview of how you can expand the networking capabilities the new Raspberry Pi mini PC “I can get five 1 Gbps network interfaces using an Intel I340-T4 PCIe NIC, but I can only get a maximum of 3.06 Gbps throughput using all five interfaces at the same time.”
You could use this setup to build a custom router or switch using OpenWRT or pfSense, or to run other specialized network setups for multiple-interface webservers, bandwidth metering, network bonding, or more!”
