STM32

After spending some time with first various AtMega 8 bit processors and then Espressif's ESP32 I decided to explore STMicroelectronics STM32 series of micro processors. Initially that seems a daunting experience. There are literally hundreds of different STM32 MCUs and understanding the differences is important in picking the right one for any given project.

STM32 Families

STM32 processors are grouped in a number of families. The following chart give a brief overview of these and the naming conventions:
