W5500 Ethernet Module with SPI Interface

The W5500 Ethernet Module with SPI Interface adds wired Ethernet network connectivity to an Arduino or microcontroller over a 4-wire SPI connection, operating from 3.3V to 5V, with a W5500 chip that handles the entire network communication protocol in hardware — so the Arduino itself does not need to run network code in software, leaving more processing power free for the actual project application. This ethernet module is an alternative to WiFi modules for projects that need a stable, permanent, cable-based network connection rather than a wireless link that can be affected by router range, interference, or congestion.

The w5500 ethernet module’s hardware TCP/IP stack is its defining feature — most WiFi-based networking options require the microcontroller to handle network protocols in software, which consumes significant RAM and processing time; the W5500 chip has its own dedicated network processor that manages packet sending and receiving independently, communicating with the Arduino only through the SPI interface to pass completed data.

The ethernet module for arduino’s wired connection also means no pairing process, no password configuration, and no wireless interference — plug in an Ethernet cable to a router or switch and the network connection is established immediately. Available from StemVolt, offering quality electronics parts at competitive prices.
