Whilst AXIOM Beta was being showcased at Chaos Communication Congress 2017, two bright developers from Germany became interested in the camera and decided to lay the foundations for a cheaper version (specifically by using a low end image sensor) of the camera for development purposes.

To reduce work, most parts of the AXIOM Beta's software should be used. Only the bitstream should be a custom development as this doesn't have to be up-streamed.
The AXIOM Micro uses a similar mechanical concept as the AXIOM Beta - An of the shelf FPGA development board is stacked on top of custom boards. However, the AXIOM Micro only uses one board to handle the camera's power management, image sensor interfacing and for holding the plugin modules.

Some lens-mounts need thick disks to be positioned between the lens-mount and a lens-mount adapter in order to achieve the correct flange distance. For example, the micro-four-thirds mount needs to be combined with the 5mm shim.
The current enclosure design for AXIOM Micro allows access to the PCB and mainly consists of cnc milled sheets of acrylic glass for the front and back side and spacers. It allows for mounting on two 15mm rig type rails.
CAD files can be downloaded here.
To develop the PCBs, simply clone this repository with:
git clone --recursive https://gitlab.com/anuejn/axiom-micro-hardware
Then use Kicad to edit the schematics and PCB.
Warning: This Project uses submodules. when you clone without --recursive Kicad wont find some libraries!
