I am considering getting some Nokia 5110 displays for use with my Arduino Nano board but I am in a pickle because I can't tell the correct way to wire it.
Some people say to power it with 3.3V and only 3.3V and to use 3.3V logic or else. But other people claim running it on 5V just fine. The data sheet for the Philips IC that controls it says that it can have a maximum input voltage of 7V so it looks like I would be fine. However, some people report abnormal behavior and short life span of the screen. If I used the circuit below except with Vcc and LED going to 3.3V, would that be OK?
