3 Features
The STM32F401 Discovery board offers the following features:
• STM32F401VCT6 microcontroller featuring 256 KB of Flash memory, 64 KB of RAM in
an LQFP100 package
• On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone ST-
LINK/V2 (with SWD connector for programming and debugging)
• Board power supply: through USB bus or from an external 5 V supply voltage
• External application power supply: 3 V and 5 V
• L3GD20, ST MEMS motion sensor, 3-axis digital output gyroscope.
• LSM303DLHC, ST MEMS system-in-package featuring a 3D digital linear acceleration
sensor and a 3D digital magnetic sensor.
• MP45DT02, ST MEMS audio sensor, omnidirectional digital microphone
• CS43L22, audio DAC with integrated class D speaker driver
• Eight LEDs:
– LD1 (red/green) for USB communication
– LD2 (red) for 3.3 V power on
– Four user LEDs:
LD3 (orange), LD4 (green), LD5 (red) and LD6 (blue)
– Two USB OTG LEDs:
LD7 (green) VBus and LD8 (red) over-current
• Two pushbuttons (user and reset)
• USB OTG with micro-AB connector
• Extension header for LQFP100 I/Os for a quick connection to the prototyping board
and an easy probing
