请问stm32f103和stm32f407这两种中引脚数量相等的型号，它们的引脚是不是兼容的，或者是说，我的一款stm32f103zet6开发板，能不能把开发板的MCU换成stm32f407zgt6，换完之后开发板就能当stm32f407zet6开发板用了？

不可以
The STM32F405xx and STM32F407xx devices maintain a close compatibility with the
whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The
STM32F405xx and STM32F407xx, however, are not drop-in replacements for the
STM32F10xxx devices: the two families do not have the same power scheme, and so their
power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F40x
family remains simple as only a few pins are impacted.

你好，我对比了一下stm32f103和stm32f407的LQFP144封装的Pinouts和pin description，pinouts有几个电源引脚不一样，其他的都一样，也就是GPIO相对应。在默认复用功能中，stm32f103中有的stm32f407都有。我的想法是，我在画板时把引脚不兼容的地方做处理，在焊板时进行选择。这样板子都可以用这两款了。

如果直接替换是不行的，毕竟部分引脚不一样，如果你能处理妥当，当然是可以的啊~
