Hi.
That’s a very vague question. What would you like to do with the ESP-EYE?
At the moment there isn’t much support for Arduino IDE and we don’t have any tutorials at the moment.
There are support for IDF, but I’m not very familiar with it:

• https://www.espressif.com/en/products/hardware/esp-eye/overview
• https://github.com/espressif/esp-who/blob/master/docs/en/get-started/ESP-EYE_Getting_Started_Guide.md
• https://github.com/espressif/esp-who/tree/master/examples

Some ESP32-CAM examples in our blog also work with the ESP-EYE by setting the right pin assignment.
Regards,
Sara
