Discovery kit with STM32F411VE MCU
Introduction
The STM32F411 Discovery kit (32F411EDISCOVERY) helps you to discover the entry level
of the STM32F4 series and to develop your applications. It is based on an
STM32F411VET6 microcontroller and includes an ST-LINK/V2 embedded debug tool
interface, ST MEMS Gyroscope, ST MEMS accelerometer + magnetometer, ST MEMS
digital microphone, audio DAC with integrated class D speaker driver, LEDs, pushbuttons
and a USB OTG micro-AB connector.
