[abandoned] Which external cam for common esp32 boards (e.g. for html videostream website widget))

Hardware

hi,
which external cam is suitable for common esp32 boards (e.g. for html videostream website widget, smart home surveillance)?
The breakout boards (e.g. like DEBO CAM ESP32, AZDelivery ESP32 Cam) have far too few free GPIOs left and so I want to use a common ESP32 NodeMCU Development Board (dualcore, 34 gpios) with built-in USB and SD slot and stacking headers.

Any suggestions?

The bare OV2640 camera, used on the ESP32CAM, does use a lot of IO pins which is why there are so few left for other purposes.

Not tried it on the ESP32 but the Arducam OV2640 uses far less IO pins.

If you dont get a response in here, maybe ask on the Espressif Forum as it is they that support ESP32, but I find thier forum layout a bit fuzzy and unclear, so maybe its one to avoid.

thank you very much, it looks fine, IIUC a couple of SPI + i2c interface pins.
Are SPI and i2c optional or additional?
Does it work with 3v3 from ESP32 or does it need 5V supply?
And is there some example code for a website by a html video stream widget available?

No idea, I said;

"Not tried it on the ESP32"

However I did test it on an Arduino DUE, which is also a 3.3V logic microcontroller, and it worked just fine.

No idea.

I had already taken a look at the website, but I think I'm going to fail desperately when it comes to installing it for Windows, and I can't find any example code there as usual for Arduino... :roll_eyes:

Please help the forum.

Which website ?

What has Windows to do with it ?

Which camera (or other) are you refering to ?

strangely I can't reload it, I think it was
https://www.arducam.com/
there was also a link to a special arducam esp32 board (UNO compatible formfactor)
https://www.arducam.com/product/b0105-arducam-esp32-uno-board-for-arducam-mini-camera-module-compatible-with-arduino-uno-r3/
with a link to a github repo with installation instructions where Windows and Linux targets are mentioned...

anyone else experienced?

[abandoned] because of ESP32's too puny memory and computing power for video processing and way too weird and confusing futile instructions.

I used the arduinos library to download arducam within that gives example sketches and they worked for me ...the look I. The folders there is a host program also I found to play the feed back for one...the other I used I set my own ip address then just enter that into your web browser realy easy to do
