Hi,
I will use the STM32L432KC nucleo board to perform some tasks. STM32 users know that this is 3.3V microcontroller. One of the tasks is to read a speed optical sensor which output a 5V square wave. I read in the datasheet that STM32L4 GPIO is 5V tolerant. But I just wonder if anyone here has worked with 5V signals on STM32.
