STM32 Tutorial #62 – STM32F402 Mystery MCU – Real life testing!

We have done a few videos about the mysterious non-existing STM32F402 MCU (Chinese market only MCU). In an earlier video we speculated that it was in FACT a STM32F401. Having received our STM32World STM32F402 development board, we finally get to put this theory to the test! Watch the video to learn the secrets of this MCU.
