That combination makes it a fit for motor-control loops, audio processing, and real-time sensor fusion where a Cortex-M3 would need to spend extra cycles in software emulation.
The 82 GPIOs in the 100-LQFP package leave room for a colour TFT display, external sensors, and a few serial peripherals without a port expander.
It uses an ARM Cortex-M4 core with single-cycle DSP instructions and a hardware floating-point unit, running at 168 MHz.
The evidence does not carry a direct comparison for the VET6 variant. Both belong to the same STM32F407 family and share the Cortex-M4 core, but the VET6 typically offers 512 KB Flash and a smaller SRAM footprint versus the 1 MB Flash and 192 KB SRAM of the VGT7. Verify the specific package and memory configuration against your BOM.
