This is the layout for my daily driver orthodox. It's based on a custom handwire keyboard that I've been using for quite some time. It's based on Plank's/Let's split layouts for the lower/raise layers. I added the shift, control/enter, alt/altgr and del to the thumb cluster.
To build the firmware run from qmk's project folder
make orthodox/rev3:rfvizarra
And to flash it, run
make orthodox/rev3:rfvizarra:avrdude
reset your keyboard pro micro while connected to the PC with a micro usb cable.
Repeat on both halves.
See install build tools then the build/compile instructions for more information.
