## Article

**INTRODUCTION**

This product is an Ethernet network module using W5500. This product is sold by several companies in China Ali Express. I could not find a company that developed this product. The 2.54mm pitch-pin header provides power and SPI interface pins. The network modules developed in China are all connected by a 2.54mm x 10 pin header. This product can be connected to several MCU development boards. STM32F103C8T6 ARM Mini system Development board of module fans development boards of Xiaomei Ge's FPGA
