Hardware migration from STM32F1 to STM32F0

series

The entry-level STM32F1xx and general-purpose STM32F0xx families are pin-to-pin

compatible. All peripherals shares the same pins in the two families, but there are some

minor differences between packages.

The transition from the STM32F1 series to the STM32F0 series is simple as only a few pins

are impacted. The impacted pins are shown in bold in the following tables.
