Which STM32???
There's a whole bunch of them, from Arm Cortex M0's to M7F's.
The M0 is extremely cheap, can be well under a buck for the chip.
The M7F has caches,memory mapping, and floating point, 216mhz clock.?
I'm currently playing with a "Blue Pill", has the STM32F103C8, $2 on ebay
? ??
Has the M3 core at 72mhz,? 64meg of flash, 20meg of ram, 12bit ADC.
Otherwise much like like the Nano, IO is primarily 3.3v with some 5v tolerant pins.
Get one that reads "PC13" in the silk towards the lower right corner (most these days do).
I got it to speak Arduino with some messing around, though not all the libraries are supported.
Arduino is a good way to get your feet wet, I may move on to the Atollic Eclipse IDE someday.

I have also replaced the UNO with an STM32
