STMicroelectronics STM32F411E-DISCO

Overview

STM32F411E-DISCO from STMicroelectronics is a fully integrated, production-ready discovery kit built around the STM32F411RE microcontroller - an Arm® Cortex®-M4 32-bit MCU with FPU, 512 KB Flash, 128 KB SRAM, USB OTG FS, and 13 communication interfaces. It supports real-time motor control, sensor hub operation, and industrial HMI development at up to 100 MHz clock frequency with ART Accelerator enabling zero-wait-state flash execution.

For engineers reviewing the STM32F411E-DISCO datasheet, STM32F411E-DISCO pinout, STM32F411E-DISCO application, or STM32F411E-DISCO equivalent, this page delivers verified technical context, key specifications, supply status, manufacturer background, and targeted FAQs - all grounded in ST's official DS10314 Rev 8 documentation and board schematic data.

Technical Context

The STM32F411E-DISCO implements a complete evaluation platform for the STM32F411RE MCU, featuring on-board ST-LINK/V2-1 debugger, MEMS sensors (LSM303AGR accelerometer/magnetometer, LPS25HB pressure sensor), and audio subsystem (MP34DT01TR-M microphone, audio jack). It enables direct firmware development via SWD interface without external tools.

Hardware design includes dedicated USB OTG FS connector, Arduino Uno V3 and ST Morpho expansion headers, user LED/button, and reset circuitry compliant with STM32F411xE power-up sequencing requirements - supporting full validation of low-power modes (Stop/Standby), ADC sampling (2.4 MSPS), and DMA-driven peripheral co-processing.

FAQ

Does STM32F411E-DISCO include a built-in debugger?

Yes - it integrates ST-LINK/V2-1, a certified CMSIS-DAP-compliant debug probe supporting SWD programming, real-time variable watch, and full CoreSight trace. No external JTAG adapter is required for firmware download or debugging.

What sensors are included on the board?

The board features the LSM303AGR (3-axis accelerometer + 3-axis magnetometer) and LPS25HB (absolute pressure sensor), both accessible via I²C. These are factory-calibrated and supported by ST's X-CUBE-MEMS1 software package for sensor fusion and calibration.

Can STM32F411E-DISCO operate in low-power modes out-of-the-box?

Yes - the board's power architecture fully exposes STM32F411RE's low-power capabilities. Example projects in STM32CubeF4 demonstrate Stop mode (9 µA) and Standby mode (1.8 µA) with RTC wake-up, validated using on-board current measurement test points.

Is the USB OTG FS interface functional without external components?

Yes - the board includes a full-speed USB OTG FS PHY, micro-AB receptacle, and necessary termination resistors. It supports device, host, and OTG roles; example code demonstrates MSC, HID, and CDC classes directly from the onboard MCU.
