Does anyone know if the RF-24G is 5V tolerant? It’s speced at CMOS levels, but for my current project, a lot of other components need to be TTL.
Pretty much no. One of my own projects involves these guys, and the first thing that Nate told me was “don’t give them 5 volt anything!” Will they survive 5 volt logic? To a degree, I suspect. But why tempt fate?

Yeah, good point. I guess I’ll use a dual rail supply then.
Thanks!
You can always try a current limitor, or a voltage divider for the input pins. The unit will need to be powered at 3.3V though.
I’ve done some pretty evil things to the test units (powered at 5V for a couple seconds, reverse powered them, etc) and they survived like troopers, but when sh^# hits the fan, it’s best not to wonder if the over-voltaged units are the thing to question.

So the old 4.7Kohm resister/capacitor/diode setup for the 5V → 3.3V connections and leave things as-is in the reverse direction?
