@ScruffR I could use it with or without headers, it doesn’t matter - whatever allows me to mount it easier.
Re: Pins, yes, it will be connected to a strip of lights, the reset button will probably be exposed to another button (unless I can find a way to mount it outward facing, and have a small hole in the wood to allow someone to stick a pencil inside to reset it). And it will be connected to a 2.1mm mounted jack for VIN/GND.
These can be connected either through directly soldering or through a Poke-in connector.
There are very little to none mechanical demands on the mount - the product is stationary, enclosed, and not exposed to water. Wood can slightly expand/contract, but that wouldn’t be a problem in this case.
The Photon does not need to be extractable, a permanent mount would be fine.
