What is it?

This is a M4/3 camera module for RPI5 based on IMX294 camera sensor. Specifically it supports the RPI boards with 4-lane MIPI, like CM4 IO board or RPI5, the driver, board KiCad files are all opensourced (see Github page for more info and quick start guide).

The thing in the box will be FourthirdEye camera sensor board + FPC cables, unlike my other camera modules IMX294 package is too large for the off-the-shelf C mount and you will need to come up with your lens design (Bring Your Own Lens Mount). An passive E-mount 3D printed adaptor step files is provided in Github page as your reference.

Given that both lens and filter are not included, this is not going to be out-of-box usage and this is targeting mostly for those who are aware of this project already, so if this is the first time you see this camera module I'll recommend you look elsewhere for better out-of-box experience. Additionally this board is not going to support any kind of electronic control mount like E-mount/EF mount.

Note that the driver and libcamera support is not in the upstream, so currently you will have to use my libcamera fork, additionally there are still quite some work on the driver side that needs some cleanup.

But currently here are the modes implemented:

0 : imx294 [3840x2160 12-bit RGGB] (/base/axi/pcie@120000/rp1/i2c@80000/imx294@1a) Modes: 'SRGGB12_CSI2P' : 3872x2180 [61.43 fps - (-20, -6)/3840x2160 crop] 4144x2184 [57.76 fps - (-4, -6)/4096x2160 crop] 4176x2184 [54.37 fps - (-4, -6)/4096x2160 crop] 3792x2840 [48.69 fps - (0, -2)/3704x2778 crop] Notes: This is with overclocked camera frontend on RPI5 (Not BCM2712 but the RP1 chipset), without overclock the RP1 limits the pixel rate to 380 Mpix/sec, so any modes that are over that Mpix/sec limits will be caped at that framerate.
