There are such third party IMX219 flex PCB modules, for example the one shown on this topic
I was thinking of having one custom made for me. But while I found the intermediate PCB schematic on the camera web page
, I haven't found the schematic for the flex PCB.
In the thread you pointed to I did put link to aliexpress.com for that custom flex PCB (model IMX219-D77), and that has the schematic:

As 6by9 pointed out there is no guarantee that such custom flex PCB will work (the D77 one has 6cm flex cable between board and imx219, while the original has less than 1cm). Since I have tested this sensor successfully with Raspberry v2 camera board in the thread, with normal framerates as well as with high framerates (>500fps with raspiraw) that missing guarantee from RPF should not be a problem.
But please be aware of 6by9's other warning wrt D77 sensor:

... nor that it would pass EMC testing (the oscillator is on the camera board and single ended, so it'll be spraying 25MHz around the place merrily if on a long flexi).
Last, but not least, the IMX219-D77 has a slightly different FoV than the original v2 board imx219 (may be good or bad):
Code: Select all
Camera Module Pixels Sensor Infrared Field of View Aperture (F) Focal Length
RPi Camera V2 original camera module 8 Mega IMX219 × 62.2 2.0 3.04
RPi NoIR Camera V2 original camera module 8 Mega IMX219 √ 62.2 2.0 3.04
IMX219-D160 8 Mega IMX219 × 160 2.35 3.15
IMX219-D77 8 Mega IMX219 × 77.6 2.0 2.96
Depending on the lens you will use, and the distance between sensor and lens, you can get better than 0.153µm/pixel resolution (of v1 camera):

The imx219-d160 sensor has 160° FoV, but you will have your own lens as you said.
Anyway, for 15$ with free shipping you get a different, short flex cable imx219, here is the schematic.
Given the much shorter flex cable, there should be no EMC problem as with the longer flex cable:

It should be easy to remove the D160 lens, and the flex cable with raw imx219 sensor (w/o lens) is really small:
