Does this means that we can use 5v devices (provided they read a 3v3 signal as high) without any risk of damaging the RoboRIO? I'm just thinking about various sensors and custom circuits that were designed for 5v that may perform differently at 3v3. They can probably be re-designed but it would be nice if that wasn't necessary.
