I have been looking for quite some time for a keyboard that can run QMK as the firmware, but that also has the number pad and navigation keys (arrows, home, ins, del, end, pg up and down).
I see many TKL and smaller keyboards, but nothing full featured. I realise part of the problem is the number of keys and available pins on the MCU, however a shift register will overcome that.
Has anybody designed one? Is there one available?
