# Newbie Using the W5500

## Question

Asked by neil1 on 2021-05-18 in Ethernet Chips.

Hi
I am new the W5500, and have an USR-ES1 to connect to the SPI on my STM32L4 processor. Can anyone point me to where a beginner of this device should go for description and information on a library to use with the STM32L4?

Many thaks
Scott

If you use iolibiray provided by wiznet and can use MCU’s SPI, there is no problem with using any MCU.
Please refer to the link below.
