NUCLEO-WB55RG or another STM32WB55 based reference design

STMDesigner · ‎2025-03-31

Hi,

I was wondering if there is a reference design available for STM32WB55 based product. I am designing a system based on this MCU using the datasheet and application notes such as AN5165, but it always helps to see implementation of existing product. One I found was NUCLEO-WB55RG, but I cannot find schematics, are they public?

If there are any other reference designs that are close enough, could someome point me to them please?

Best regards,

STMDesigner

As usual, they are on the 'CAD Resources' tab of the Product Page:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
