NoticeW5100 Ethernet Shield V1.0
Contents
Overview
W5100 Ethernet shield V1.0 is a WIZnet W5100 breakout board with POE and Micro-SD designed for Arduino platform. 5V/3.3V compatible operation voltage level makes it compatible with Arduino boards, leafmaple, and other Arduino compatible boards except Mega boards.

Installation
When install W5100 Ethernet shield V1.0 to Iteaduino, please check the operation voltage level of development board. If the voltage is 3.3V (IFLAT32,Leafmaple), set the Operation Level Setting switch to 3.3V. If the voltage is 5V(Arduino), set the Operation Level Setting switch to 5V.
Iteaduino communicates with both the W5100 and SD card using the SPI bus. This is on digital pins 11, 12, and 13 on the UNO/Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general I/O. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output.
Note that because the W5100 and SD card share the SPI bus, only one can be active at a time. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the W5100, set digital pin 10 as a high output.
Indicator LED
The shield contains a number of informational LEDs:
- LNK: indicates the presence of a network link and flashes when the
shield transmits or receives data
- FEX: indicates that the network connection is full duplex
- SPD: indicates the presence of a 100 Mb/s network connection (as
opposed to 10 Mb/s)
- RX: flashes when the shield receives data
- TX: flashes when the shield sends data
- COL: flashes when network collisions are detected
