Hi, does anybody know the internal resistance of the digital pins? I want to ensure that my input voltage of a sensor does not exceed 3.3V.
Many thanks!

The maximum pin sinking current is 10mA but it is advisable to keep well below this. The effective on resistance depends on which pin it is! Most pins are around 150 Ohms using the ShieldBuddy add-in's configuration.
