THat is the neat thing about the STM32 range. There is the take $2 chip on the "bluepill" and also the M4 chips with 5X faster clocks and FPUs
Here is a nice chart showing STM32 products sorted be speed, power and size. None of these cost much mover $20. The larger ones are Arduino Ono pin compatable so off the shelf shields fit. The price is right and there are so many of these on the market. But that $2.50 STM32F103 board most things. I buy them 10 at a time.
