Discovery kit with STM32F407VG MCU
Introduction
The STM32F4DISCOVERY Discovery kit allows users to easily develop applications with
®
®
the STM32F407VG high-performance microcontroller with the Arm
Cortex
-M4 32-bit
core. It includes everything required either for beginners or experienced users to get started
quickly.
Based on STM32F407VG, it includes an ST-LINK/V2-A embedded debug tool, one ST-
MEMS digital accelerometer, one digital microphone, one audio DAC with integrated class D
speaker driver, LEDs, push-buttons and a USB OTG Micro-AB connector. Specialized add-
on boards can be connected by means of the extension header connectors. The
STM32F4DISCOVERY Discovery kit comes with the STM32 comprehensive free software
libraries and examples available with the STM32CubeF4 MCU Package.
