Negative voltage on GPIO

[claudio...@gmail.com]

Hi to all,

Can I use negative voltages such as input values on Blackbone green GPIO?
(These values should be interpreted as 0 logic level)

What is their minimum value? Could I apply -5V?

[Wulf Man]

No.

Thank you for the reply.

But what is the minimum voltage that can be applied to a GPIO without breaking them? 

[Gerald Coley]

0V or Ground.

No negative voltages of any amount.
