Design with ENC28J60 Ethernet Board in Cirkit DesignerThe ENC28J60 Ethernet Board is a versatile network module that enables Ethernet communication for embedded systems. It integrates a Microchip ENC28J60 Ethernet controller and PHY (Physical Layer Transceiver), providing a cost-effective solution for adding network connectivity to microcontroller projects. This module is commonly used in applications such as home automation, IoT devices, and web server implementation in microcontroller-based systems.
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.

Ethernet.h library is used to handle Ethernet communication.mac array holds the MAC address for the Ethernet board.EthernetClient object is used to create clients that can connect to a specified internet IP address and port.Ethernet.begin(mac) initializes the Ethernet shield with the provided MAC address.Ethernet.h library's diagnostic functions to check for connectivity and obtain IP address information.Q: Can the ENC28J60 Ethernet Board be used with a 5V microcontroller? A: Yes, but a level shifter is required to convert the 5V signals to 3.3V to avoid damaging the ENC28J60.
Q: Does the ENC28J60 support Power over Ethernet (PoE)? A: No, the ENC28J60 does not natively support PoE. External circuitry would be required to implement PoE functionality.
Q: Can I use multiple ENC28J60 boards with one microcontroller? A: Yes, you can use multiple boards with a microcontroller by using separate Chip Select (CS) lines for each ENC28J60 board.
Q: How do I assign an IP address to the ENC28J60 Ethernet Board?
A: The IP address can be assigned programmatically using the Ethernet.begin() function in your code. It can also be set to obtain an IP address automatically via DHCP.
