a complete re-write or just a few pins ?
All the port numbers are correct. the peripherals however are located on other ports, so if you're used to a peripheral being at PA8, then it could be on PB5 on the other microcontroller.
only the crystals, power, usb & DACS seem to always be on the same pins.
So if you make an upgraded bluepill like this,all the port labeling is correct . (if you'd upgrade a maple mini however... all the peripherals indicated on it won't be correct).
