You can find one PCB pic from below pics.
That PCB is old one. It doesn't support Keymap tool.
But New version can support Key Mapping and full SMT.
Yes right but LK-1800fe's PCB is new one.
Leeku makes new PCB that it can support L3 layer Key Mapping.
New PCB will produce from one of my factory guild for this GB.
We have decided to make renewal it 2 days ago. Just 3 days past.
Nobody doesn't knows this news except Leeku and me.
So everybody don't worry about it.
Some of guys from GH, they have met some weeks ago when Leeku visit for his business trip.
At that time, they don't know this news even though Leeku, neither.
He just started to redrawing for new PCB.
You do not need to worry about it anymore.
2 weeks later you can see new one here.
Have a good keyboarding.

I'll be back soon with LK-1800fe. (include Leeku's new PCB)
