Quick Overview

Plug in module with a Ethernet to SPI converter based on the WIZnet W5500 chip including vertical RJ45 jack


Product Description

A small “Connector-on-Board” plug in module with the WIZnet W5500 chip and breadboard friendly footprint. The module converts SPI to Ethernet and includes a vertical RJ45 jack for top side connections on a baseboard with a small size of only 39 x 23 mm.

The module contains a 8 pin 2.54 mm pitch connector for the SPI connection and the power supply. It can be easily attached to a microcontroller which is capable of SPI. After adding the module to any existing project the project is ready for any IoT application.

This module has been produced and developed by our partner ESoPe in Germany.
