The ENC28J60 Ethernet LAN Network Module is an Ethernet controller that connects to any development board through the SPI protocol. It uses the Microchip ENC28J60, a well-known Ethernet IC, to function as both a server and a client. Most MCUs may be directly connected to this Ethernet LAN module.

Specifications:

• ENC28J60-I/SO Ethernet chip
• 25Mhz Crystal
• Power LED
• Size: 56x34mm
• Fully Compatible with 10/100/1000Base-T Networks
• 3.3 V power supply pin.
• Integrated MAC and 10 Base-T PHY
• Supports Full and Half-Duplex modes
• SPI Interface with Clock Speeds Up to 20 MHz
• The network interface of the board RJ45 Connector HR911105A.
