What is it?
This is a M4/3 camera module for RPI5 based on IMX294 camera sensor.
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 mount is a matt-black CNC’d CS mount with M28.5 filter sized IR650 filter embedded, so you can easily swap it with similar sized filter. Note that C/CS mount can fit a M4/3 sensor, however most of the C/CS mount lens may not have image circle large enough for the M4/3. The reason to still stick with C/CS mount is that it is easier to adapt to other 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:
- 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 capped at that framerate.
