I have a microcontroller and am considering buying a radio module. Every module I find online has a maximum operating voltage of 3.9. My microcontroller runs at 5V.
I want to be able to exchange data between both devices but I'm afraid if I hook up the pins directly then I'd blow up the radio module since it can't handle 5V.
I heard about level converters but I'm not sure which IC to buy. I'd rather buy something that's commonly available.
I also thought of a LDO voltage regulator from 5V to 3.9V to drive VCC of the radio module but I don't know if that's efficient.
Can someone point me in the right direction? I'm also limited to DIP IC's since I don't work with smd.
