I tried to find some information about the electronics on the board of the camera, but like a lot of cheap Chinese electronics it seems the used chip is not very documented, or at least not in English.
There seems to be only one chip doing all the work, there are traces going from the camera module to it, and the USB lines are also connected directly to the chip.
When calling lsusb in the command line it reports a 1e4e:0110 Cubeternet device for the camera. The manufacturer is listed as Etron Technology, Inc., but I was unable to find any datasheets on their website.
The code on the component itself didn't help much either:
If anybody has some more information about this particular device it would be welcome.
From the front the camera looks like it's missing a lot components. The diodes D1-6 are connected to Q2 which looks like a typical SMD transistor footprint, so technically it's possible to add some LEDs to the camera board, which is nice I guess...
On the back there is some code, possibly some production code:
Also there is an 8-pin unpopulated footprint (U5), seemingly not a necessary part, omitted to lower production costs. The traces go to the main chip, perhaps some memory?
I don't want to spend too much time reverse engineering the hardware for now, as it seems to be working well enough to make a stereo camera with a pair of those.
