Hey all,
Just reading the specs page again, and i noticed the Digital IO pins a rated at 3.3v but are 5v tolerant.
Just a simple question, will using 5v Input or Output reduce the life expectancy of the device and is using 3.3v safer/recommended over 5v? Or does it simply not matter?
Thanks in advance,
Stuart.

"Tolerant" means that's possible without any pain.
I'd love the humans were "tolerant" each other as the Netduino pins are with 5V.

Biggest fault of Netduino? It runs by electricity.

For the digital I/O's, it just doesn't matter. For analog I/O's it does. They are 3.3V, not 5V tolerant. An important one to keep in mind

Thank you both for your input. Just had to make sure I was doing what is recommended.
