The STM32F411RET6: For a typical sensor-fusion or motor-control application running FreeRTOS and a HAL, the flash footprint lands around 80–120 KB, leaving roughly 300 KB for application code and data logging buffers.
The DMA engine offloads data transfers from the core, keeping the CPU free for control-loop math or protocol stacks.
The STM32F411VET6 (100-pin LQFP) and STM32F411CEU6 (UFQFPN-48) share the same core and memory but differ in package and I/O count. Within the same 64-LQFP footprint, the STM32F401RET6 offers a lower-cost option with 84 MHz max speed and 256 KB flash, though pin compatibility should be verified against the specific BOM position.
