Picture not contractual. CS43L22, audio DAC with integrated class D speaker driver Description Eight LEDs: The 32F401CDISCOVERY Discovery kit allows LD1 (red/green) for USB communication users to easily develop applications with the LD2 (red) for 3.3 V power on STM32F401 high performance MCUs with ARM Four user LEDs: Cortex -M4 32-bit core. It offers everything LD3 (orange), LD4 (green), LD5 (red) and required either for beginners or experienced LD6 (blue) users, to get quickly started. Two USB OTG LEDs: Based on the STM32F401VCT6, it includes an LD7 (green) V and LD8 (red) over- BUS ST-LINK/V2 embedded debug tool, a gyroscope, current an e-compass and digital microphone ST MEMs, Two pushbuttons (user and reset) an audio DAC with an integrated class D speaker USB OTG with micro-AB connector driver, a USB OTG micro-AB connector, LEDs and pushbuttons. Extension header for LQFP100 I/Os for a quick connection to the prototyping board and an easy probing Comprehensive free software including a variety of examples, part of STM32CubeF4 package or STSW-STM32136 for legacy Standard Libraries usage February 2016 DocID025209 Rev 3 1/4 For further information contact your local STMicroelectronics sales office. www.st.comSystem requirements 32F401CDISCOVERY System requirements Windows OS (XP, 7, 8) USB type A to Mini-B cable Development toolchains IAR EWARM (IAR Embedded Workbench ) Keil MDK-ARM GCC-based IDEs (free AC6: SW4STM32, Atollic TrueSTUDIO ,...) Demonstration software The demonstration software is preloaded in the board Flash memory. It uses the user button and the LEDs to switch from a simple blinking of the LEDs to an indication of the movements of the board. When connected to a PC with a second USB cable, the board is recognized as a standard mouse. The latest versions of the demonstration source code and associated documentation can be downloaded from the www.st.com/stm32f4-discovery webpage. Ordering information The Discovery kit with the STM32F401VC MCU (order code STM32F401C-DISCO) is replaced by the Discovery kit with the order code STM32F411E-DISCO. 2/4 DocID025209 Rev 3
