Introduction

This application note is intended for system designers who require a hardware implementation overview of the development

board features: power supply, clock management, reset control, boot mode settings, and debug management.

It details how to use the STM32U0 microcontrollers, named STM32U0, and describes the minimum hardware resources

required to develop an application using these MCUs.

This document also includes detailed reference design schematics with the description of the main components, interfaces, and

modes.
