The minimum focus of the 64MP camera is about 8cm, so it limits even more the size of objects that you can scan. The 16MP does down to about 6cm, which is already tight. My plan is to make a scanner with a moveable camera arm, so that I can adjust the camera position (distance from object) that I like. But ymmv, as they say in the movies ;)

Hi I have just received my 64MP camera, and have tried to integrate it with OpenScan. It is not easy at all, for me it is impossible. The benefits of the higher pixel resolution is clear, you can digital zoom, and still have the same number of pixels as the 16MP at full resolution. Of course the speed will not improve, if anything the larger images may slow it down a bit. I think the quad camera setup is great, but outside of the scope of OpenScan. It is too costly a setup to make the opensource/hobby level device a likely candidate for many people. Thomas, over to you, dude. We are all sitting at the edges of our seats for you to surprise us with a 64MP-supporting Firmware. Gruess MC

Hoi Sabine! I guess nothing stops you from going bigger, but you will have to *think* about it a bit. The Pi mounting and the holes for the ringlight/camera part cannot be changed, so you can't just scale to 150% and print. Also, the field of view of the autofocus arducam is quite wide, you will likely crop your images quite a bit, unless you scan wide objects. Having said that, I found the arducam minimum focus distance to be almost unusable for the Mini, I put some 3cm M3 spacers to move the camera back a bit. Good luck with your build, do you have a working mini already?
