Topic: How to tell if you damage I/O pin on the DUE? (Read 698 times) previous topic - next topic

I recently realized that the radio module I was using outputs 5V signals from the Do/Di to my Rx/Tx. This radio module has been running for days, and is still running and working. I know the Arudino DUE is limited 3.3V for digital I/O pins, but does that include rx/tx pins too?

Is there a way for me to check if I damage by board or perhaps the rx/tx pins? Everything is working as it should but I want to know if this is going to be a problem.



You have exceeded its rating, it could easily be degraded and might fail totally in
the future.  Or it might not.  The only way is to test the device for years!

Thanks for the reply. I guess I'll just have to wait and see!
