| | 3 | This is a very small SPI connected Ethernet TCP/IP module using the [http://www.wiznet.co.kr WIZnet] W5100 chip. |
| | 4 | W5100 is a hardwired TCP/IP processor. |

| | 11 | I have started this project before this summer. I have ordered manufacture of PCB on September, and I received it on October. |
| | 12 | I spent 3 hours to solder. I regret that I choose 1005 (metric) SMD LCR devices. |
| | 13 | The main chip is 0.4mm pitch 80 pins LQFP. |

| | 17 | It required a small fix to make the board work. |
| | 18 | The bug was about the center tap of transformer. |

| | 20 | This module works with Arduino. It is compatible with the Arduino Ethernet library in the Arduino 0012 distribution. |
