Design with Module Ethernet W5500 in Cirkit DesignerThe Module Ethernet W5500 is an embedded network module that enables Ethernet communication for electronic devices. It is widely used in IoT applications, allowing devices to connect to local networks or the Internet to send and receive data. This module is particularly useful for projects that require network connectivity without the complexity of Wi-Fi configuration.
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.
Open Project in Cirkit Designer
This circuit connects a Raspberry Pi 5 to a W5500 Ethernet module, enabling Ethernet connectivity. The Raspberry Pi communicates with the W5500 via SPI interface, and a resistor is used to manage the reset signal for the Ethernet module.

This circuit features an ESP32 microcontroller interfaced with a W5500 Ethernet module for network connectivity, a DHT22 sensor for measuring temperature and humidity, a ZMPT101B module for AC voltage sensing, and an Adafruit SHTC3 sensor for additional temperature and humidity readings. The ESP32 also controls a 4-channel relay module for switching external devices. The sensors and Ethernet module communicate with the ESP32 via GPIO pins, with the W5500 using SPI and the SHTC3 using I2C. Common ground and power lines are shared among the components.

Ethernet.h library's functions to check for Ethernet hardware status.Q: Can the W5500 module be used with a 5V microcontroller? A: Yes, but a level shifter is recommended to protect the 3.3V logic of the W5500 module.
Q: How many simultaneous socket connections can the W5500 handle? A: The W5500 can handle up to 8 independent socket connections.
Q: Is it possible to use the W5500 module without an external library?
A: While possible, using an external library such as the Ethernet.h library simplifies the programming and is recommended for most users.
