I send in an earlier question about this. I could not get this module to perform any differently with AI Thinker hardware then the original CameraWebsever (Module 1). _ I would like to resolve this.
However I tried this with Freenove ESp32 Wrover and it works just fine. I would like to try unit2 with sensors and web cam but what I2C pins can I use on the for Wrover. ?

Hi.

What issues do you get with the AI-Thinker?

You can use any pins you want as long as you modify the following lines:

#define I2C_SDA 14
#define I2C_SCL 15

I wasn’t able to program the AI -Thinker with any other sketch in the book other than the camera web server. Strange, I accommodated the IO0 and GND LOOP correctly. I found these devices to be unreliable ( I tested several of them). The one I did get to work the Module 1 now reports a camera problem!
anyway the Freenove ESP32 works fine, and I going to used it for Module 4 unit 2 and the I2C lines 14 and 15 you recommended. This Freenove also has a SD-Card interface
thanks
best

Hi.
Yes. The Freenove is better.
But, at the time we wrote the eBook, that model didn’t exist yet.
Let me know if you need further help.
