Microcontrollers with Built-in Ethernet

Ethernet-Enabled Microcontrollers Overview

Microcontrollers with Ethernet support are widely used for IoT, industrial control, and embedded applications. Below is an overview of popular models that integrate Ethernet capabilities.

Available Models and Key Features:

2. Adding Ethernet to Microcontrollers with Ethernet Shields

For microcontrollers without built-in Ethernet, Ethernet shields are a practical option. These shields usually connect via SPI, making them compatible with popular microcontrollers like Arduino and ESP8266.

3. Common Ethernet Modules

In addition to shields, standalone Ethernet modules, such as the W5100 and W5500, provide a flexible way to add Ethernet support to custom boards.

4. Power over Ethernet (PoE)

Power over Ethernet (PoE) enables both power and data to be transmitted over a single Ethernet cable, making it ideal for devices that need to operate without a nearby power source. PoE works with devices compliant with IEEE 802.3af or 802.3at standards.

Using PoE with Microcontrollers

For microcontrollers, PoE can be added using PoE-capable Ethernet shields or adapters. Some Ethernet shields, like the Arduino Ethernet Shield 2, have PoE options available using an external PoE module.

Example of PoE Adapter

The W5500 Ethernet module with PoE is a popular option for adding PoE support to microcontrollers. This module allows the microcontroller to be powered directly through the Ethernet cable, which can simplify deployment in remote or hard-to-access areas.

5. Advantages of Using Ethernet

6. Example Projects

Project 1: Web Server with Arduino Ethernet Shield

Use an Ethernet shield to create a web server that controls LEDs or reads sensor data.


// Arduino Web Server with Ethernet Shield
#include 
#include 

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 1, 177);
EthernetServer server(80);

void setup() {
    Ethernet.begin(mac, ip);
    server.begin();
    Serial.begin(9600);
    Serial.println("Server is ready");
}

void loop() {
    EthernetClient client = server.available();
    if (client) {
        // Handle client request
    }
}

Project 2: MQTT Client with ENC28J60

Use the ENC28J60 module to connect to an MQTT broker for sending sensor data and receiving commands.

8. Conclusion

Microcontrollers with built-in Ethernet capabilities provide a robust solution for developing networked applications. By selecting the right microcontroller for your project, you can leverage the advantages of direct internet connectivity, making your devices more efficient and responsive.
