Test the keymat!

[Kolbász]

I believe the ones near the shoulder buttons are test connections for the speakers.

I think I finally spotted the other four vias (near the volume wheel) in the schematic diagram. Sheet 19/51 of 4G mainboard schematics, labels "DACL" and "DACR". It says "solder in/outs for testing". So yeah, these vias carry audio signals.

The headset jack in the PCB on the board is too far in. That's already fixed on the current prototypes

Was this the last stop?

Yes, I've just shipped it back to ED.

Old habits die hard, eh?

@EvilDragon, please post pics and thoughts.

OK, so this is probably a bit of necroposting, but I'm still really curious what @EvilDragon thought of the well traveled box and it's additional contents.

Also - is there any chance I can get a couple of keymats without the gel coating? I want to frame them.

A well, right, still need to unpack it

What do you mean with Gel coating?

Everyone who received that box was so anxious to open it ... all but one.

In the collection of keymats there was one example with lettering that did not have the clear plastic lense caps on top of the keys. Likely an early test piece. If you have a box of those sitting around, I ask that you toss one or two of the otherwise unusable pieces in with my prototype. If they don't exist or if it is in any way arduous to find and include them, skip it.

But, you should look through the contents if you're ever even semi-bored. I even found the exterior of the box interesting with it's layers of postage & labels and blacked out names.
