I made a wireless replacement PCB for the GMMK Pro.
If you take the SquishyTKL and chop off the F-row, you get the SquishyFRL.
I mean, that's also exactly how I did the PCB layout; I just deleted the F-row and rerouted a few things and I was done!
Similar to the Squishy65, this is a TKL-sized board with gasket mounting.
What's special about this is that only the 60% section of the TKL is actually gasket mounted.
This is a wireless 60% PCB I made. Featuring the hineybush h60 outline so it can be drop-in for different keyboards.
