Sorry for the derail, but I think the TRIM is actually 15mm so at least that one should be safe. All the same, I couldn’t resist trying to fit an Avert (which for some reason I convinced myself was shallower than it actually is). Anyway, with a little lift from some washers it sort of does…
I don’t love this as a long term solution though so I’ll probably notch the PCB to fit around the bump at the bottom of the frap case – luckily there’s lots of room at the edge before the traces so there’s little risk. Still I’ll have to be delicate since I don’t want to disassemble the module. (Tips from DIYers welcome BTW!)
