1894 is a keyboard PCB supporting 60% layouts. It is a revised version of the Voyager60 pcb by ai03 that supports a JST connector instead of usb-c and has perimeter cutouts for gasket support. The Voyager60 and therefore the 1894 is compatible with ai03's polaris QMK implementation and as such this is just a copy with edits to update the name.
Make example for this keyboard (after setting up your build environment):
make atxkb/1894:default
