Design with ENC28J60 Ethernet Module in Cirkit DesignerThe ENC28J60 Ethernet Module is a versatile network communication module that allows microcontrollers to connect to an Ethernet network. It is based on the ENC28J60, a standalone Ethernet controller with an industry-standard Serial Peripheral Interface (SPI). This module is commonly used in embedded systems for network communication, enabling devices to access the Internet or communicate on a local network. It is particularly popular in the DIY and hobbyist community for its ease of use with platforms like Arduino.
This circuit integrates an STM32F4 BlackPill microcontroller with an ENC28J60 Ethernet Board to enable Ethernet connectivity. The microcontroller communicates with the Ethernet board via SPI, with connections for power, ground, and SPI signals (SI, SO, SCK, and CS). The provided code is a basic template for further development.

This circuit features an ESP32 microcontroller interfaced with a W5500 Ethernet module for network connectivity, a DHT22 sensor for measuring temperature and humidity, and an Adafruit SHTC3 sensor for additional temperature and humidity readings. The ZMPT101B module is connected to the ESP32 for voltage measurement in an AC power line. The ESP32 manages data collection from the sensors and communicates with the Ethernet module, likely for data logging or remote monitoring purposes.

Ethernet.h library is used to interface with the ENC28J60 module.mac array holds the MAC address for the Ethernet module.EthernetClient object is used for network communication.Ethernet.begin(mac) initializes the Ethernet module with the specified MAC address.Q: Can the ENC28J60 module be used with a 5V microcontroller? A: Yes, but a level shifter is required for the SPI lines to ensure proper logic level conversion.
Q: Is it possible to use multiple ENC28J60 modules with one microcontroller? A: Yes, you can use multiple modules by assigning different chip select (CS) pins for each module.
Q: How do I assign a static IP address to the ENC28J60 module?
A: You can assign a static IP using the Ethernet.begin(mac, ip) function, where ip is the desired static IP address.
Q: What library should I use for the ENC28J60 with an Arduino? A: The standard Ethernet library may not support the ENC28J60. Use a compatible library like UIPEthernet or EtherCard for Arduino.
