TRDB-D5M additional information

Hello!

I have some questions about TRDB-D5M (Terasic 5 Mega Pixel Digital Camera Package):

1. What type of CMOS sensor is used in this daughter card?

2. What lens type is used here (its characteristics - focal length, diaphragm and availability to adjust it) and can I replace original one with my own?

P.S. Would appreciate some test images, made by this camera.

Thanks a lot.
