Simple to build kit to add Ethernet to Teensy 4.1
Need a soldering iron of course. The 6 pin headers don't have enough pins to give a good grip so needed a small band to hold them in place when testing out on the workbench. For building into a box recommend a small dab of silicon adhesive to keep them in place. Teensy 4.1 with Ethernet is awesome, well worth getting this add-on. To confirm an active Ethernet connection I try to get a connection with an Internet Time server at startup, as per one of the examples :)

Teensy 4.1 NativeEthernet.h
You'll know if you need this and it looks the same as the one for sale on PJRC's site. The library for this is NativeEthernet.h. Library appears to be bundled Teensyduino from 1.53, and there are sketch examples under NativeEthernet (for Teensy 4.1). Mine seems to work fine testing with NativeEthernet>WebServer example. Soldering was fine but it's quite tight around other components on the Teensy board so care and clean tips were required.
