Since the F303 was a drop-in upgrade from the F072, all the pinouts remained
the same.
I have attached portions of the H and H4 schematics - the SD card interface?
from the uP is the same for both boards.

Then possible try build H version vs SD Card support, possibly in future i do it
At this moment i get one problem RTC clock on STM32. Then use internal oscillator not run then power off, and not possible fix it, so timer settings not valid after power on
For fix this need use external oscillator for RTC on MCU pin
Pin 3 - PC14 - OSC32_IN
Pin 4 - PC15 - OSC32_OUT
Easy way to install it use P3 connector and olc clock 32768 oscillator
For additional need enable use LSE by software.
But need detect installed external osc, and if it not present enable internal mode (but in this mode clock not show correct time).
At this moment i only enable LSE, it correctly run, not reset on power off (only if remove battery)
