USB OTG FS with micro-AB connector

■

Extension header for all LQFP100 I/Os for 
quick connection to prototyping board and easy 
probing

The STM32F4DISCOVERY helps you to discover 
the STM32F4 high-performance features and to 
develop your applications easily. It includes 
everything required for beginners and 
experienced users to get started quickly.

Based on the STM32F407VGT6, it includes an 
ST-LINK/V2 embedded debug tool, two ST 
MEMS, digital accelerometer and digital 
microphone, one audio DAC with integrated class 
D speaker driver, LEDs and push buttons and an 
USB OTG micro-AB connector.

A large number of free ready-to-run application 
firmware examples are available on 
www.st.com/stm32f4-discovery to support quick 
evaluation and development.
