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.
