Jon, Thanks for yours always informative posts. I think someone should come up with a HDMI ==> CSI (MIPI ) interface board for these OrangePI PCs... it would be owesome...., instead of these gspca crap... they have now.
Jon, maybe you can help me... I am looking for an 720p or 1080p camera, H264 compressed video, and with Wired ( and WI-FI a plus ), with AUDIO input... something that has also AUDIO as input and not just video. If you know any cameras with that capability, and in the US$50 range, let me know.
