W5100 Arduino Ethernet Shield Module Network Expansion Board

Product details

• Product: Arduino Ethernet Shield
• Microcontroller: Wiznet W5100
• Version: latest
• Dimension: 7cm x 5.4cm x 2.4cm
• Connection with Arduino: using long wire-wrap headers which extends through the shield

Arduino Ethernet shield is based on W5100 ethernet chip which provides a network stack capable of both TCP and UDP. The module allows Arduino to connect with internet without operation system. This ethernet module supports 4 simultaneous socket connection.

RoboElements has the latest version of Arduino Ethernet shield so it has a micro SD card slot and a reset controller. By using the SD card, it stores the data serving over the internet. Reset controller ensures that the W5100 Module is properly reset on power-up.

Features

Ethernet shield allows Arduino to connect to the internet

Has SD card slot to save data

No soldering required to connect with Arduino. Directly plug puzzle board

Compatible with all the version of Arduino

Connection speed: 10/100Mb

No external power needed

Arduino communicates with both W5100 and SD card using SPI bus

Shield provides standard RJ45 ethernet jack

LED and indication

PWR: Board is powered

LINK: the presence of network and flashes when transmits or receives data

100M: the presence of 100Mb/s network connection

FULLD: a network connection is a full duplex

COLL: flashes on detection of network collision

RX: flashes when receives data

TX: flashes when transmits data

Instrcutions

Ethernet library comes in Arduino 0019

SD card library is not yet included in Arduino distribution.

W5100 and SD card share SPI bus, so only one can be active at a time

While using both peripherals in the programme, corresponding libraries should be taken care of.

If one of the peripherals used in the programme, then the maker needs to explicitly deselect it. To do so

For SD card: set pin 4 as output and write a high for it

For W5100: set digital pin 10 as a high output
