Description
The ENC28J60 Ethernet LAN Module is a reliable and affordable networking solution designed for microcontrollers that require wired Ethernet connectivity. Built around the Microchip ENC28J60 single-chip Ethernet controller, this module provides a full 10Mbps Ethernet interface via a standard SPI communication bus.
It includes an onboard crystal oscillator, voltage regulator, RJ45 connector with integrated magnetics, and status LEDs for link and activity indication. The module operates from 3.3V logic, making it suitable for Arduino (with level shifting), ESP8266, ESP32, STM32, PIC, AVR, and most embedded systems.
This module is perfect for IoT systems that require stable and secure wired network connectivity, especially in environments with heavy interference where Wi-Fi is unreliable.
