W5100-SPI board

This is a very small SPI connected Ethernet TCP/IP module using the WIZnet W5100 chip. W5100 is a hardwired TCP/IP processor.

Arduinoと接続

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

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

実装しました

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