Compatibility

Designed for Arduino Nano (may work with other 5V/3.3V boards with same footprint)

Ethernet Chip

Typically uses W5100 or ENC28J60 (depends on the model)

Connection

10/100 Mbps Ethernet (RJ45 port)

Protocols

Supports TCP/IP, UDP, DHCP, ARP, ICMP

Power Supply

5V (from Arduino Nano or external power)

Interface

SPI communication with the microcontroller

LED Indicators

Link/Activity status LEDs

Pins Used

Uses digital pins (D10-D13 for SPI) – may vary by shield version

Dimensions

Matches Arduino Nano footprint (~18mm x 45mm)

Library Support

Works with Ethernet.h (W5100) or UIPEthernet.h (ENC28J60)

Applications

IoT projects, remote control, data logging, network-connected devices
