- | The Ehternet Board is designed as an Paper-PCB, too. | + | 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. |
