STM32C071GBU6 PA2 (pin 8 on the UFQFPN28 device) is configured as ADC_IN2.  What voltage can be expected when the pin is unloaded?

Welcome @ToddGilbert32, to the community!

Well - if the pin is initialised as ADC_IN2 and nothing is connected to it, the pin floats and no defined voltage is to be expected there.

Does it answer your question ?
