Interfacing arduino with ov7670

Hi all,

I already bought a 24 pins OV7670 camera module (640x480 Pixel lens OV7670 CMOS Camera Module+24p Socket 2.5V-3.0V).But I cannot find its datasheet. Today, I found another module on the internet named "Waveshare OV9655 Camera Module" which very much looks like OV7670 module.

It would be my pleasure if someone has any experience working with those modules, share them with me and let me know if the both module are the same. I mean can I use the datasheet of OV9655 for 24 pins OV7670?

Thank you in advance for your help and reply.
