# Talking to W5500 using SPI

## Question

Asked by SGMAKS on 2024-04-05 in Ethernet Chips.

Hello,

I want to talk to the W5500 (on my custom board) via SPI using an external driver or module where I can send/receive SPI commands/data. Perhaps, a USB to SPI module and an application where I can send data (like TeraTerm used for UART). Are they any products and software’s that you make/recommend for this? Or alternative methods?

Thank you!

Would be better if you explain the application of the W5500 in your product. Otherwise browse the WIZnet catalog for available modules to play with.

just plain old Ethernet communication via TCP protocol using RJ45 connector where SPI lines are in communication with an MCU.
