Ethernet Network Module ENC28J60 (Big)

The ENC28J60 Ethernet Board is a compact and reliable module designed for easy integration with Arduino and other microcontrollers that support the SPI communication protocol. It is based on the ENC28J60 Ethernet controller developed by Microchip and is widely used in wired networking projects. This module operates at 3.3V while supporting 5V-tolerant interface lines, making it compatible with many popular microcontroller platforms. Communication with the host microcontroller is handled through SPI, ensuring fast and stable data transfer. With this Ethernet board, you can build applications such as web servers, network ping responders, and internet-connected home automation systems. The integrated RJ45 connector with built-in magnetics simplifies network connections and helps keep the board compact.

Arduino Code Example Using ENC28J60

The EtherCard library is commonly used to interface the ENC28J60 module with Arduino. After installing the library in the Arduino IDE, you can upload the following example code to test Ethernet communication and web requests.


#include "EtherCard.h"

static byte mymac[] = { 0x74, 0x69, 0x69, 0x2D, 0x30, 0x31 };
byte Ethernet::buffer[700];
static uint32_t timer;
const char website[] PROGMEM = "www.google.com";

static void my_callback (byte status, word off, word len) {
  Serial.println("Response:");
  Ethernet::buffer[off + 300] = 0;
  Serial.println((const char*) Ethernet::buffer + off);
}

void setup () {
  Serial.begin(57600);

  if (ether.begin(sizeof Ethernet::buffer, mymac, SS) == 0)
    Serial.println("Ethernet controller not found");

  if (!ether.dhcpSetup())
    Serial.println("DHCP failed");

  ether.printIp("IP: ", ether.myip);
  ether.printIp("Gateway: ", ether.gwip);
  ether.printIp("DNS: ", ether.dnsip);

  if (!ether.dnsLookup(website))
    Serial.println("DNS lookup failed");

  ether.printIp("Server: ", ether.hisip);
}

void loop () {
  ether.packetLoop(ether.packetReceive());

  if (millis() > timer) {
    timer = millis() + 5000;
    ether.browseUrl("/foo/", "bar", website, my_callback);
  }
}
