Choose W5500 for speed and ENC28J60 for cost savings.

Voltage Compatibility

Check if the module works with 3.3V or 5V logic. Most modern boards are 3.3V compatible.

Ensure your Arduino voltage matches the module requirements.

Interface Type

Most modules use SPI for communication. Ensure your microcontroller has available SPI pins.

SPI is faster than I2C and widely supported.

Socket Support

Some chips like W5500 support multiple sockets. This allows multiple simultaneous connections.

Single socket chips are fine for simple web server tasks.

Power Consumption

Modules need sufficient current especially under load. 200mA is a safe minimum.

Use a stable power supply to avoid network drops.

Physical Size

Compact modules save space but shields offer easier integration. Consider your enclosure size.

Smaller PCBs fit better in tight projects.

Connector Type

RJ45 connectors should be durable and standard. Isolation transformers protect your board.

Check for transformer presence on the PCB.

Documentation

Good libraries and tutorials speed up development. Look for popular chips with community support.

Popular chips have better Arduino library availability.

How to Use and Care for Your Arduino Lan Ethernet Module

Connect the module using SPI pins including MOSI MISO SCK and SS. Power it with 3.3V or 5V depending on the model.

Install the appropriate Arduino library such as Ethernet or EthernetUDP. Update your sketch to include your IP settings.
