We are all in search of the fastest in a wireless router, to give ourselves the best connectivity to the world. But what about the slowest? Gigabit Ethernet may not be for everyone, as Matt Deeds demonstrates with bit-banged 10baseT Ethernet on a Raspberry Pi Pico 2W.
The project is written in Rust, and is in part a port of an earlier project. It makes use of Ethernet magnetics, but the rest of the works is all done in software. He says it’s full-speed on transmit and reduced speed on receive, but we’re guessing if you’re using 10baseT in 2026 then speed isn’t your number one concern anyway. It provides a WiFi router as well as a wired connection, making it possibly the cheapest Ethernet to wireless solution possible.
We like projects that extract the last ounce of power from a part to make it do something its designers never intended. In this case we’ve seen a few other bit-banged Ethernet projects before, even another on the Pi Pico.
