While the design itself probably isn't "secret", the guy that did the layout/routing would probably be bound by NDA not to distribute it (or use it for commercial gain yada yada).jbeale wrote:Are PCB layouts for consumer products considered secret? If this PCB is covered by an NDA, I'd like to point out that anyone with an x-ray machine (or sandpaper and patience) can find out where all the traces are, on every layer.

I can't release details but I can give you a simple answer: DON'T!sharix wrote:How much of the board can be cut off? I'm pretty sure about the green areas, yellow needs confirming.
There are two large golden pads on the sides of the ribbon connector which can probably be cut to a smaller size, and at the right end there are two small holes which I don't know if they have any purpose.
I suspect the PCB designer didn't say a word. Just quietly fell off his chair and spluttered a bit when Gert asked the questionI can ask the PCB designer if that is the case as I am seeing him this evening but he
is likely to be bound by an NDA.
My kid has a reusable drinking straw, fairly heavy-duty which looks about the right size. I think any plastic tubing of the right size could work fine, just cut to the length you want.sinuz wrote:What kind of spacer could i use to mount the camera board to something? M2 standoffs seem te be very rare.
I can imagine a fixture with pogo-pins can test a whole set of panelized boards at once, without a need to manually attach a cable to each one (although mine did come with the cable already inserted).

This allows testing of the board without having to use a cable.
Maybe you haven’t noticed, but the camera housing itself is stuck to the board with a patch of adhesive and comes off fairly easily. Nothing you’d want to align an optical axis with.RaspISteve wrote:Guys,
I know its a bit late now but from the drawing it would appear that the lens axis is just off line from the adjacent mounting holes. It would make lining this thing up with any supplemental lens system a whole lot easier had these holes been moved a bit or perhaps elongated.
My point? once spent far too long trying to line up subsystems where the important bits didn't line up with anything else.
If chewing gum, bluetak or duct tape is the preferred method of fixing then I can see my issue fails.
