How do i connect my ESP-32 CAM with Arduino?

Other Hardware 3rd Party Boards

Hello there!

I want to connect my ESP-32 CAM with Arduino UNO, but I don't want to program it. I have a TTL adapter, so I can program the ESP-32 CAM. What I want to do is that I want the ESP32 CAM to communicate with the Arduino UNO. Is it possible?

You can use UART serial to transfer data from one to the other, but a logic level converter is required to convert the 3.3V logic to 5V logic, and vice versa.

Connecting the UNO and the ESP32 directly will cause them to malfunction, or even be damaged.

So, i cant just connect the module to Arduino by 5v directly?

You can, but that may destroy one or the other. Your choice.

Ok, thanks.

I got curious.
Why do you want to connect an ESP32_CAM to an Arduino?

7

You must program the Uno if you want it to receive data.

For a project.

the ESP32-CAM has some limited IO capabilities is there any need for a UNO?
if you need more IO than the ESP32-CAM supports connect it to another microcontroller using WiFi, e.g. a ESP32 Devkit which has plenty of IO capabilities
