ENC28J60 SPI Ethernet Module

The ENC28J60 Ethernet Module is a compact, standalone network interface solution for connecting your microcontrollers (AVR, PIC, ARM, ESP32) to a local area network. Based on the Microchip ENC28J60 chip, this controller integrates an MAC and a 10BASE-T PHY compliant with the IEEE 802.3 standard, providing full Ethernet functionality without requiring a heavy-duty processor.

This breakout board simplifies network integration via its high-speed SPI interface (up to 20 MHz). Its inputs are 5V-tolerant, making it directly compatible with 5V platforms like Arduino without the need for level shifters. It features a standard RJ45 connector with an integrated network transformer for reliable wiring.
