Ethernet-Board

The Ehternet Board is designed with the cheap Ethernet IC ENC28J60. Cause the IC is running on 3.3V one need the Quad Buffer 74ACT125 to convert the 5V signal in a 3.3V signal. The Board was designed for the Paperduino-Uno and therefore a 3.3V voltage power converter is on the board, too. The pins on the LAN socket must be modified to match the holes on the strip board.

Here you find the library and some examples: ether_28j60.zip
