Why one of the GPIOs (PB7), configured as output, is giving only 1.58V instead of 3.3V when it is set? I have the STM32L432KC nucleo.

You have something else on the pin driving it low, and they are fighting? Check the schematic.

I don't have anything connected to the pin. I'm measuring with no load.

I don't have the controller right now to check. But I'm almost sure that should be the case. Thank you. I should've paid more attention to the schematic in the user manual.
