Boron Digital Output HIGH pin Voltage only 2.8v not 3.3v


I am using the most basic form to set a digital output on pin A5 to HIGH but with a volt meter i am only getting 2.8v not 3.3v as the device states for digital high output.

FYI a reading off the 3v3 pin shows 3.3v perfectly.

Is there anything i need to set extra to get 3.3v as the output with digitalWrite(led, HIGH); ?

thank you much !

Welcome to the community :+1:

Have you got anything other than your volt meter connected to that pin?
Do you get the same readings from other pins?
