AN2586 Application note STM32F10xxx hardware development: getting started Introduction This application note is intended for system designers who require a hardware implementation overview of the development board features such as the power supply, the clock management, the reset control, the boot mode settings and the debug management. It shows how to use the High-density and Medium-density STM32F10xxx product families and describes the minimum hardware resources required to develop an STM32F10xxx application. Detailed reference design schematics are also contained in this document with descriptions of the main components, interfaces and modes.
