W5100 Ethernet Network Shield W5100 Ethernet Expansion Board with SD Card Slot for Arduino UNO MEGA2560

W5100 Ethernet Shield

The Arduino W5100 Ethernet Shield utilizes the Wiznet W5100 ethernet chip, enabling an Arduino board to access the internet. This chip includes a robust network (IP) stack that supports both TCP and UDP protocols. With the addition of a Micro SD card slot, the W5100 Ethernet Shield Network Expansion Board can handle up to four socket connections simultaneously.

Employ the Ethernet library to create sketches that establish internet connections through the shield. The shield itself connects to an Arduino board using extended wire-wrap headers, preserving the original pin layout and permitting additional shields to be stacked on top.

The latest update of the board reveals the 1.0 pinout for Arduino UNO rev 3. This W5100 Ethernet Shield lets you swiftly connect your UNO R3 board to the internet. Simply attach the module to your Arduino board, link it to your network using an RJ45 cable (not provided), and follow a few easy steps to begin controlling your surroundings via the internet. Additionally, it enables you to connect your Arduino UNO 328 or MEGA 2650 1280 to a network or the internet while also accessing and storing files on a Micro SD Card.

The W5100 Ethernet Shield is equipped with a standard RJ-45 connection, complete with integrated line transformer and Power over Ethernet capability. It also features an onboard micro-SD card slot, allowing for convenient storage of network-served files. This shield is fully compatible with the Uno and Mega boards when utilizing the Ethernet library. The SD Library provides access to the onboard microSD card reader, with SS located on Pin 4. Please note that earlier versions of the shield included a full-size SD card slot, but this is no longer supported.

Additionally, the shield features a reset controller to properly reset the W5100 Ethernet module upon powering up. Previous versions of the shield did not work with the Mega and required manual resetting after power-up.
