I'm building a circuit in which I am going to interface a bluetooth module to a 16f628a. The module runs on 3.3V and not on 5V and because it is a relatively expensive module, I don't want to burn it up or mess it up by applying 5V to it.
Can somebody clue me in on how to do this exactly? Am I supposed to use a diode of some kind? If somebody could tell me a part #, sample schematic and general theory, I would be most appreciative.
Thanks!
Ilan
