Question

Microcontrollers

There is a sensor with 3.3v logic and atmega328 (the one that is in the arduino) and all this is powered by a 3.3v stabilizer, do you need a level converter or will everything work fine without it?

Answer 1

Not

Answer 2

atmega328 converter is not needed. But in any case, read the datasheet for your sensor
