- Identify this example, its board class and pin limitations.
Before this introduction
STM32 names a microcontroller family. NUCLEO-F401RE is an example development board using STM32F401RE and an onboard ST-LINK debugger. Arduino-style connector shape does not make its GPIO or voltage limits identical to UNO. Header labels must be mapped to actual MCU pins; reserved/debug roles require checking the exact manual.
