I have verified the pin assignments for the STM32F072 vs the STM32F303 for the LQFP-48 package from the ST datasheets. Unless I made a mistake they match exactly. I was very careful, but it would be nice if someone else checked also.
I read the assignments off the schematic and then checked them against the datasheet for the STM32F303 part.
The STM32F303CCT6 shows from Digikey at $4.37 quantity 100 vs $2.62 for the current part quantity 100 price. For 2400 it is $3.20 vs $1.92 so a $1.28 uptick in cost in production quantities.
I'm going to take hugen up on his offer to provide a unit with the STM32F303CCT6 part installed. Having triple the RAM and twice the flash should make it possible to add a lot of interesting features.
Units without the LCD and with provision for control via the USB port would be fantastic with a Pi Zero.
Have Fun!

BTW I did verify that the port auto-negotiates the speed and am able to connect to the console at 115200.
