What is STM32F401RBT6？
The STM32F401RBT6 is Arm® Cortex® -M4 32-bit core which can operate at the frequency of up to 84 MHz. The STM32F401RBT6 is one of the Arm Cortex – M4 core which includes FPU (Floating point unit) unit. A floating-point unit (FPU), also known as a math coprocessor or numeric coprocessor, is a specialized coprocessor that manipulates numbers more quickly than the basic microprocessor circuitry. The STM32F401RBT6 features power saving mode allows the design of low-power applications. The STM32F401RBT6 can operate in temperature range of – 40 to + 125 °C.
NUCLEO-F410RB is development board with STM32F41RBT6. This development board is used in academics and research for fast prototyping. It has inbuilt ST-Link/V2 which makes its compatible to communicate with software like MATLAB/Simulink.
