for this low price (below 10 Bucks) it performs well as an “overall” webcam with fish eye optics.
Camera module was purchased on Amazon, in search for something that could be used in Medical scenario to take LED illuminated close up pictures (like really close up… from skin etc.) on GNU Linux, but unfortunately this cam module does not seem to be suitable for this scenario (can not focus closer than 3cm, image blurry, also the LED failed to turn on (maybe missing a switch somewhere?)

closer
best near focus was around 2-3cm, but it is still not possible to read the year the coin was produced…
Alcor Micro Usb Reader Driver
which the camera of a mobile phone such as the huawai 6p (Nexus) can do with ease from 20cm apart (coin from 2009)
but it has to be added, the huawai 6p users lasers to focus on an object, and that does not always work so great (trial and error, takes time so not so suitable for fast snapshots)
details:
- (+) cam sensor is not soldered directly on circuit board (which is the case for for the otherwise very good Logitech C920) would prevent putting it in elongated small casings)
- (+) works out of the box with GNU Linux (Debian 10)
- (+) near field focus is okay up to 5cm (1cm would be nice 🙂
- (+) resolution of 1600×1200
- (-) LED does not turn on? X-D

bit more expensive but might be interesting as well (but guess can also not do very close focus)
