3 slot backplane for RCA COSMAC Microboards

Ethernet Shield for Teensy 3.5 and 3.6.

See this Kickstarter update for more info.

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.

Warning: you must solder the LAN8720A’s center pad. This chip will not work if only the outside 24 pins are connected.

A future version of this board may include Power Over Ethernet support…..
