Quick Overview

Ethernet to SPI converter based on the WIZnet W5500 chip with 8 pin data connector and 8 pin SPI and power supply connector.


Product Description

A small 'stamp' sized “Break-out-Board” module with the WIZnet W5500 chip and 900mil distanced pin headers on a breadboard friendly footprint. The module converts SPI to Ethernet with a small size of only 26x23 mm.

One the left side of the module contains connectors to the SPI interface, the right side has connectors to the power supply and the RJ45 jack. Any microcontroller capable of setting up a SPI connection can be connected to the module. After adding a microcontroller and a RJ45 jack the module is ready to be used for any IoT application.

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