Paul Stoffregen of PJRC designed this shield as a Kickstarter reward earlier this year:

Ethernet Shield for Teensy 3.5 and 3.6

Please understand this shield has very limited software support at this time. However, Manitou’s early benchmarks show excellent performance we can someday hope to achieve as the software matures.

PaulStoffregen has shared the board on OSH Park:
