Experience with Ethernet for Teensy 4.1?

[veroelectric]

We're very experienced with designing hardware and firmware around the Teensy 4.0 but we now have a project that calls for ethernet which is having us consider the 4.1. I'm rusty on the Ethernet spec so I have some homework to do, but wondering what people thought of the 4.1 with ethernet generally.

(not intended at all as sarcasm): It works !! I've used it to put one of my Teensy-based projects on my home network. The current recommendation is to use the QNEthernet library instead of the NativeEthernet library, as QNEthernet is actively being supported, & the author is very active on this forum.

I use it very frequently (for both commercial and non-commercial projects) and it’s very stable. There are lots of additional features in the QNEthernet library that other Arduino-style libraries don’t have. It can be installed via the Arduino IDE, but my preference is to use PlatformIO.

The project Readme has a complete feature list.
See: https://github.com/ssilverman/QNEthernet

There are also lots of examples. (Be aware that there are some problems with the current IPerfServer example.)

For commercial-level stuff, feel free to reach out to me privately.
