I'm seeing two options for swapping the microphone:
1) If we already have to run two wires for the mic, why not run three? One of them would just then be 5V from BlueSaab.
2) On the BlueSaabMic PCB, we could include a buck converter to drop 12V to 5V for the mic bias. We'd still need to pull 12V from somewhere (what do the "Fasten Seat Belts" lights run on?)

As far as demand goes - Even if it doesn't turn into a proper revision, the best option in that case is just forgoing the main module revision and creating a new mic module. I've just decided that's what I'm going to do in either case.

No more Saab!? That's alright, it happens. I'll check out Circuit Maker, but I've got a pro license for Eagle, and I'm pretty comfortable in it. It also plays nicely with OSHPark.

Karlis, please let me know how you get on with that microphone! After this week I should have some time outside of work to play around, so I'll probably start ordering parts/kits. Fingers crossed Microchip gets back to me about that free sample...
