Both buffers must be powered from +5V, not +3.3V or whatever the MCU uses. In addition, the MCU must be tolerant of 5V signals being applied to its I/O pins (the CORE_STM32F4 module is tolerant)--otherwise it will damage the MCU! | Both buffers must be powered from +5V, not +3.3V or whatever the MCU uses.
