SPIDER Automation Ethernet W5100 R3 Shield | Ethernet & SD Shield | Arduino Internet & Network Communication
Description
The SPIDER Automation Ethernet W5100 R3 Shield allows an Arduino board to connect to the internet, turning your microcontroller into a powerful networked device. Based on the reliable Wiznet W5100 Ethernet chip, the shield provides an internal network IP stack capable of handling both TCP and UDP protocols, supporting up to four simultaneous socket connections.
Designed with a standard RJ-45 connection and an onboard micro-SD card slot, this shield lets you host web pages, serve files over a local network, or log remote sensor data. Featuring a stackable R3 pinout layout and an integrated reset controller to ensure stable power-up sequencing, it integrates smoothly into standard Arduino and Genuino development ecosystems.
Key Features
- Wiznet W5100 Core: Hardware network processor supporting TCP/IP stack protocols without heavy firmware overhead.
- Simultaneous Multi-Socket: Capable of managing up to four active socket connections at the same time.
- Integrated Micro-SD Card Slot: Onboard storage reader accessible via SPI (Pin 4 SS) for hosting web files and data logs.
- Stackable R3 Layout: Extended wire-wrap headers preserve the pin configuration so other shields can stack on top.
- Built-In Reset Controller: Ensures the W5100 Ethernet module resets correctly upon power-up for stable operation.
- Standard RJ-45 Interface: Built-in line transformer supporting 10/100Mbps network communication speeds.
Benefits
- Simplifies IoT Connectivity: Direct integration with official Arduino Ethernet libraries drastically reduces development time.
- Enables Local Web Servers: Serve HTML pages, images, and configuration files directly from the onboard micro-SD card.
- Flexible Expansion: Pass-through header pins allow you to combine network capabilities with sensor or display shields.
-
Reliable Power Sequencing: Onboard reset circuitry eliminates manual reset requirements on power-up.
Applications
- IoT Web Servers: Hosting live sensor dashboards and control pages accessible via a standard web browser.
- Remote Industrial Monitoring: Transmitting telemetry data and receiving remote commands over local area networks (LAN).
- Network Data Loggers: Recording high-frequency sensor events directly onto micro-SD cards or uploading them to servers.
- Smart Home Automation Hubs: Interfacing Arduino microcontrollers with smart switches, lights, and routers via Ethernet.
-
Educational Networking Labs: Teaching students TCP/IP stack principles, socket communication, and web protocols.
