First board rendering! 6 toggles and an area to be used as shutter button on the back of the phone. Have always found it awkward to use my thumb for the onscreen shutter, think this will be more natural.

Also, the BOM is complete so I can make a more accurate estimate of costs. First estimate was a bit on the safe side, think I can make this OH for 45 for small batch (<10) and 40 for larger (=>10). Updated in first post.

This is also a WIP issue, but I was just thinking about the location and functionality of the dip switches. Like, how easily they switch their position. Because, if you have tight jeans for example, you will maybe get accidental switching. Another thing is usability with covers and so on.
Yes, I think you have already thought this issue. And no, I don't have any ideas on how to solve this. But yes, I'm interested and I think 50€ is okay.

but i don't know if this will be an issue, because the switch i will be using is totally new to me!

6 boards are on the mail -from the usa- so ordering parts today! 4 boards will be available for sale, if it all works.

Some parts are in - all except for back-ordered switches itself.
This is a GPIO expander, cant believe how tiny it is!
(I have done it, what you need is a good microscope, flux and very tinypointed smd iron, but you do not do many of these in an hour...)

With good flux, no need to have so small irontip, just solder one pin, then flux, then some solder on tip and start from other side if chip, and just swipe with iron over the pads...
Or paste with little extra flux and hot air (or bbq-reflow).
Making large via middle of thermal pad makes soldering easier (also rework gets easier, at least with multilayer boards)
