The Arduino Ethernet Defend permits an Arduino board to connect with the web. It’s primarily based on the Wiznet W5100 ethernet chip. The Wiznet W5100 offers a community (IP) stack able to each TCP and UDP. The Ethernet W5100 Defend Community Enlargement Board w/ Micro SD Card Slot helps as much as 4 simultaneous socket connections.
Use the Ethernet library to put in writing sketches which connect with the web utilizing the defend. The ethernet defend connects to an Arduino board utilizing lengthy wire-wrap headers which lengthen via the defend. This retains the pin format intact and permits one other defend to be stacked on high.
The latest revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO board. This Ethernet Defend connects the UNO R3 board to the web in mere minutes. Simply plug this module onto your Arduino board, join it to your community with an RJ45 cable (not included) and comply with just a few easy directions to begin controlling your world via the web. means that you can join your Arduino UNO 328 or MEGA 2650 1280 to a community or the web AND retrieve or retailer recordsdata on a Micro SD Card!
The Ethernet Defend has a normal RJ-45 connection, with an built-in line transformer and Energy over Ethernet enabled. There may be an onboard micro-SD card slot, which can be utilized to retailer recordsdata for serving over the community. It’s appropriate with the Uno and Mega (utilizing the Ethernet library). The onboard microSD card reader is accessible via the SD Library. When working with this library, SS is on Pin 4. The unique revision of the defend contained a full-size SD card slot; this isn’t supported.
The defend additionally features a reset controller, to make sure that the W5100 Ethernet module is correctly reset on power-up. Earlier revisions of the defend weren’t appropriate with the Mega and have to be manually reset after power-up.
This module is appropriate with following Arduino variations: Arduino UNO Arduino MEGA
