Master Control Project » Ethernet Shield

This is the standard Arduino Ethernet Shield. I made one modification, which was to shorten the legs on the headers and ICSP header, so it would sit as low as possible above the Proto shield. The Ethernet shield communicates with SPI and to make it work with both the Arduino Uno and the Mega, this shield uses the ICSP port to handle most of it’s work. For this reason, I needed to add an upside-down stacky header to the Proto shield’s ICSP port.
