Hey there I'm relatively new to coding and very new to any electrical components and the ESP32. I'm currently working on a STEM fair project and I'm planning on using AI recognition through Edge Impulse for images so I bought a camera.
I have an ESP32-WROOM-32 and an OV2640. I do not have the ESP32 that is specified to work with cameras, is there any alternative methods or do I have to buy an ESP32-CAM?
thanks !!
Welcome to the forum kayleed!
This is not really about Arduino and it might have been more appropriate to ask on an ESP forum, but the ESP32-CAM is just an ESP32 with the same OVA2640 camera bolted on and quite a few pins missing, or rather, not presented.
However, the ESP32-Cam has the connector for the cam interface which the ESP32 WROOM does not.
One thing to bear in mind with the ESP32-CAM is that it requires a separate USB adapter, such as the FTDI one shown in this tutorial, to program.
Ah, I see! I was more so wondering as well how would you connect the ESP32-WROOM with the OV2640? Because on the ESP-CAM it has a unit where you can easily attach the OV2640 into it, yet the ESP32-WROOM does not have that function.
It is also possible to get a WROOM board with a cam interface. Just search "Freenove". I expect that many of the pins will be unavailable when a camera is connected and it does seem to be a bit more expensive.
Ah alrighty then, tysm!! :]
Yes the ESP32-WROOM does have that function.
All you need to do is follow the schematic diagram for the ESP32CAM, which is available, and use the right connector for the OV2640 camera.
could you elaborate further, please? I'm unsure of what you're referring to,, sorry ^^'
thanks !!
I moved your topic to a more appropriate forum category @kayleed .
The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.
In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.
Thanks in advance for your cooperation.
Elaborate in what way ?
Take a look at the schematic of the ESP32CAM, that will show you the circuit and connections you need to replicate.
However, its far easier to just buy an ESP32CAM.
Ohhh my apologies for the confusion!! Thank you
