The Arduino-compatible W5100 Ethernet Shield is an expansion board designed to integrate seamlessly with Arduino UNO and MEGA boards, allowing easy and efficient Ethernet network connectivity. This shield is ideal for projects that require network communication, such as embedded web servers or web clients.

Thanks to the provided library, you can configure the network via software, making it easier to adapt to different environments and local networks. In addition, this improved version includes a socket for micro-SD memory cards, allowing you to store and serve files directly from the shield, expanding the possibilities of your projects.

Main features:

Compatible with Arduino UNO and MEGA boards.
Includes a micro-SD card socket for storage and embedded web server use.
Automatic reset controller for the W5100 chip, ensuring reliable startup without the need for manual reset.
Communication via SPI bus through the ICSP connector.
Exclusive use of specific digital pins: 11, 12, 13 (Duemilanove) or 50, 51, 52 (MEGA) for SPI; pin 10 to select W5100 and pin 4 for micro-SD.

Typical use:

Create embedded web servers for IoT projects.
Connect Arduino to local networks to send or receive data.
Store and serve files from the integrated micro-SD card.

Compatibility and considerations:

The Arduino board is not included and must be purchased separately.
The SPI bus is shared between the W5100 chip and the micro-SD card, so only one can be used at a time; it is important to manage this in the code.
On Arduino MEGA, pin SS (53) must be configured as an output for correct SPI bus operation.

With this shield, your Arduino projects gain connectivity and functionality, making it easier to create applications connected to the internet or local networks with integrated storage.

Customer Questions & Answers

What are the exact dimensions and weight of the Ethernet Shield W5100, and what is included in the box?

The Ethernet Shield W5100 measures approximately 68 mm × 53 mm × 23 mm and weighs around 35 g. The standard box contents are the Shield board; the Arduino base board and any additional cables are not included.

What real-world applications is the Ethernet Shield W5100 especially useful for compared with other shields?

The Ethernet Shield W5100 is ideal for applications where a reliable wired Ethernet connection is required, such as embedded web servers and remote monitoring systems based on a local network. Compared with WiFi shields, it offers lower latency and greater stability in industrial environments or where there is electromagnetic interference.

Which Arduino boards are fully compatible and what connection requirements should be considered?

It is compatible with Arduino UNO, Duemilanove and MEGA, provided the SPI connection is respected (pins 11, 12, 13 on UNO/Duemilanove; 50, 51, 52 on MEGA) and pins 10 (Ethernet) and 4 (micro-SD) are assigned correctly. On MEGA, pin 53 must be set as an output, even if it is not used as SS.

What limitations are there when using the Ethernet and micro-SD connections on the shield at the same time?

The W5100 and the micro-SD reader share the SPI bus, so only one can be used at a time. Trying to access both simultaneously causes conflicts. It is recommended to alternate access in software and disable the unused SPI device by changing the relevant CS pins.

What are the critical points to consider for the durability, maintenance and warranty of the W5100 Shield?

Durability depends on avoiding electrostatic discharge, overcurrent on the SPI bus and use outside 0–70 °C. It requires no maintenance beyond regular cleaning. Warranty varies by supplier, typically 6–12 months. Spare parts are not commonly available, so careful handling is recommended.

Is the Arduino board included with the W5100 Ethernet Shield?

No, the Arduino board is not included and must be purchased separately.

What is the micro-SD card socket on this shield for?

It allows you to store and serve files from the micro-SD card, which is useful for creating embedded web servers or storing data in Arduino projects.

Is this shield compatible with Arduino MEGA?

Yes, this improved version is compatible with Arduino MEGA using the provided library from Arduino 0019 onwards.

Can the W5100 chip and the micro-SD card be used at the same time?

No, both share the SPI bus, so only one can be used at a time. It is necessary to manage this in the code.

Which pins does the W5100 Ethernet Shield use on Arduino UNO?

It uses digital pins 11, 12 and 13 for SPI, pin 10 to select the W5100 and pin 4 for the micro-SD.
