STM32F407VET6 Development Board Cortex M4The STM32F405xx and STM32F407xx family is based on the high performance Arm Cortex M4 32 bit RISC core operating at a frequency of up to 168 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 STM32F405xx and
