Guys, I have a small PS2 keyboard.  Can I ask, will it support operations at 3.3volts?

This topic has a solution.

In my experience, some keyboards work at 3.3V (generally the newer ones) and some do not (generally the older ones). Some keyboards can be a little unreliable at 3.3V

 

Try it and see...

 

Unless the manual explicitly states that 3.3V is within specification, then the only 100% sure option is to assume 5V only.

None of the 10+ PS2 keyboards that I have tried would work at 3.3v.   All needed +5.0V.
