Design with USR-ES1 W5500 lite in Cirkit DesignerThe USR-ES1 W5500 Lite is a compact Ethernet module designed to provide a simple and efficient way to connect microcontrollers to the internet. It is built around the W5500 chip, which integrates a full hardware TCP/IP stack, enabling reliable and high-speed Ethernet communication. This module supports multiple socket connections, making it ideal for applications requiring simultaneous data streams.
This circuit enables Ethernet connectivity and device control through an ESP32 microcontroller. It uses the W5500 Ethernet module for network communication and controls an 8-channel relay module for switching external devices or loads.

This circuit serves as a multi-protocol communication hub featuring two ESP8266 NodeMCUs for processing, each connected to a LoRa Ra-02 SX1278 for long-range wireless communication. One NodeMCU is also connected to an RS-485 module for serial communication and a W5500 Ethernet module for network connectivity, with MB102 modules supplying power.

This circuit features an ESP32 microcontroller interfaced with a W5500 Ethernet module, a DHT22 temperature and humidity sensor, and a 2-channel relay module. The ESP32 is configured to communicate with the W5500 module via SPI for network connectivity, read sensor data from the DHT22, and control devices through the relay module. The purpose of this circuit is likely for environmental monitoring and control over a network.

The USR-ES1 W5500 Lite module is straightforward to use in embedded systems. Below are the steps and best practices for integrating it into your project.
Below is an example of how to use the USR-ES1 W5500 Lite module with an Arduino UNO to create a simple web server:
#include <SPI.h>
#include <Ethernet.h>
// MAC address for the Ethernet module
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
// IP address for the module (adjust as needed)
IPAddress ip(192, 168, 1, 177);
// Initialize the Ethernet server on port 80
EthernetServer server(80);
void setup() {
// Start the serial communication for debugging
Serial.begin(9600);
// Initialize the Ethernet module
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// Manually configure IP address if DHCP fails
Ethernet.begin(mac, ip);
}
// Start the server
server.begin();
Serial.print("Server is at ");
Serial.println(Ethernet.localIP());
}
void loop() {
// Listen for incoming clients
EthernetClient client = server.available();
if (client) {
Serial.println("New client connected");
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
Serial.write(c);
// Check for end of HTTP request
if (c == '\n' && currentLineIsBlank) {
// Send HTTP response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("Connection: close");
client.println();
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<h1>Hello from USR-ES1 W5500 Lite!</h1>");
client.println("</html>");
break;
}
if (c == '\n') {
currentLineIsBlank = true;
} else if (c != '\r') {
currentLineIsBlank = false;
}
}
}
// Give the client time to receive the data
delay(1);
client.stop();
Serial.println("Client disconnected");
}
}
