One of the reasons i was looking forward to the Due with its SAM3X8E mcu was the integrated Ethernet MAC. Because of this EMAC the only component an ethernet shield would need to have was a simple PHY and a RJ45 jack with magnetics, alleviating the need for the relatively expensive and power hungry Wiznet chip on which the current ethernet shields are based.
Unfortunately it seems the Due designers didn’t bother wiring the EMAC pins of the SAM3X8E to a pin header. In the schematic there is an ETH header that serves as a breakout for the EMAC pins, but in the board file this header is left out and the EMAC pins are terminated.
Quite a missed opportunity imo, or are the designers planning on releasing another board with this ETH header populated sometime in the future?
