STM32F103VET6 development board

According to the figure above, stm32f1 is divided into four types according to the size of flash memory, namely “low density”, “medium density”, “high density” and “ultra-high density”, and then there is another “interconnection type”. The flash size of stm32f103vet6 we used is 512k, so it belongs to the “high density” type.

What we need to do this time is to draw the principle of stm32f103vet6.

When drawing, see the data sheet of STM32F103. This datasheet can be found on ST’s website. Remember, it’s a data book, not a reference book. ST’s official website supports Chinese, which is convenient for friends with poor English.
