Description

The STM32F411xC/xE devices are based on the high-performance Arm^® Cortex^® -M4 32-bit RISC core operating at a frequency of up to 100 MHz. The Cortex^®-M4 core features a Floating point unit (FPU) single precision which supports all Arm single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The STM32F411xC/xE belongs to the STM32 Dynamic Efficiency™ product line (with products combining power efficiency, performance and integration) while adding a new innovative feature called Batch Acquisition Mode (BAM) allowing to save even more power consumption during data batching.

The STM32F411xC/xE incorporate high-speed embedded memories (up to 512 Kbytes of Flash memory, 128 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB bus and a 32-bit multi-AHB bus matrix.
All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers including one PWM timer for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces.
The STM32F411xC/xE operate in the – 40 to + 125 °C temperature range from a 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications.
These features make the STM32F411xC/xE microcontrollers suitable for a wide range of applications. (from ST)

Pay attention in the STM32411 series the pins 10 and 41 aren’t 5v tolerant (red square in the pinout diagram)

This board type offers a socket to the bottom to add and External SPI Flash, and SPI1 CS/SCK/MISO/MOSI (PA4/PA5/PA6/PA7) are Routed to footprint for external flash.
