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