Keyboard Pcb Schematic. For case files drawings see dotdash32 s github. For firmware files see the qmk github.
The key matrix is a grid of circuits underneath the keys. It has its own processor and circuitry that carries information to and from that processor. I took the arduino pro micro schematic removed the 5v regulator and tx rx leds and mapped the gpio pins.
This does not however limit the number of pressed keys at the same time in all cases.
It has its own processor and circuitry that carries information to and from that processor. You also no longer have to really consider the pcb design aspects anymore since all of it will have been done for you on the pro micro or teensy so you can just autoroute everything. Depending on the matrix layout and controller used 2 keyboards with 2kro may behave very differently. For case files drawings see dotdash32 s github.
