The Wiznet chips are arguably the easiest and most straightforward way to get a Teensy, or just about any Arduino compatible development board, on the internet. Ever since the W5100 in the first Arduino Ethernet shield, these chips have been the weapon of choice for most tinkerers. The small-footprint, Wiznet-provided Wiz820io, based on the W5200,
To me one of the biggest nuisances with Arduino is the blocking behavior of their standard Ethernet library. I use Ethernet a lot in my projects, not to say constantly, and with the default library my application would just be sitting there doing nothing while the Ethernet connection is being set up. This can even
