This is an ethernet shield for the Teensy 3.6 and adds a transceiver to the T3.6's ethernet interface.
The shield also includes a POE module that means you can power your 3.6 from power over the connected ethernet cable (This does require a 802.3af enabled ethernet switch or injector to work).
The entire shield fits in the same footprint size of the Teensy 3.6, but because it covers the T3.6's program button an additional button has been added to the board so that you don't have to unplug the shield to get access to it.
The POE outputs 5v from the supplied Power from the ethernet cable which is then passed into the Vin of the T3.6
NOTE This supplies power to your Teensy so you will need to cut the VUSB connector or otherwise you risk blowing up your USB port, and Teensy!

Current Lead time is 4-12weeks as the 5v module is not yet available
