Question

Can we directly connect the Arduino’s 5V power supply to the OV7670 Camera Module?

(a) Yes

(b) No

The question was posed to me by my college director while I was bunking the class.

I'm obligated to ask this question of OV7076 Camera Module topic in portion Interfacing of Sensors, Actuators, and Other Modules of Arduino

Answer 1

Right choice is (b) No

The best explanation: The OV7670 Camera Module has a voltage rating of 3.3V so if we are to connect it to the 5V Arduino output, it will damage the internal circuit for the module. So we need to add a potential divider in the area to bring the voltage down.
