The STM32F401 Discovery board has been designed around the STM32F401VCT6
microcontroller in a 100-pin LQFP package.
Figure 1 illustrates the connections between the STM32F401VCT6 and its peripherals (ST-
LINK/V2, pushbutton, LED, Audio DAC, USB, ST MEMS gyroscope, ST MEMS
accelerometer + magnetometer, ST MEMS microphone, and connectors).
Figure 2 and Figure 3 help you to locate these features on the STM32F401 Discovery
board.
