mk1 C920 rework video instructions
Reworking Logitech C920 camera is not difficult, but you should have right tools and some tinkering skills. After dissecting original camera, save 4 screws to reuse for securing PCB inside new case. For full instructions see video below.

New C920 wiring
Recently updated C920 webcam version was released featuring new PCB. These changes introduced two unexpected issues: wiring is different and new PCB has mechanical interference with aluminium rework kit back plate.
If you rework webcam by yourself, please use pin-out diagram as pictured below to solder wires.
| Test point | Signal |
| TP24 | VCC |
| TP26 | USB D+ |
| TP25 | USB D- |
| TP27 | GND |
Interesting note - looks like new PCB release was rushed, spot mirrored J2 designator.

Old C920 wiring
Route USB wires as indicated in this diagram. I found Kynar monolithic wires are the best – small and easy to solder. 5 wires will be used USB D+, D-, GND, Power. Shield also has to be soldered.
USB connector is available on the other side of PCB and it is surface mount type. Therefore it will be easier to use test pins. While GND is not available as test pin I recommend making pad by yourself. You can also use other places to solder GND wire, it is just my recommendation. Scrape green soldering mask with scalpel to access GND.
mk2 C920 PCBA wiring
Camera kit has internal USB-C type connector also back plate has features to use USB-C cable with lock screws.
Prepare USB adapter
Cut and strip included Kynar wire in 4 pieces.
Solder prepared wires to USB-C adapter (please note do not solder a wire to the left most reserved pad on USB-C adapter)
C920 PCBA to USB adapter wiring
There are at least two C920 board major versions with different test point layouts. Identify your board and solder wires accordingly.
New C920 board wiring
While component placement is different, same Test Pin (TP) arrangement is valid for C930e cameras.

Mounting a filter
Logitech C920 comes with IR low pass filter installed. Without this filter camera becomes sensitive to Infrared light. In order to maintain the same functionality you should install filter with same specifications. If you wish to use camera for night vision purposes, leave it as is – don’t install any filter. In some other cases you might want to see only Infrared light. In this case install another filter. To install filter stick few strips of double sided adhesive tape and drop filter inside.

C920 vs C930
Recently Logitech ditched h.264 support for most of their cameras. Original C920 has only MJPEG and YUYV compression. If you need on board h.264 codec, please use C930 camera.
