Litl is an easy to build 40% keyboard using only through hole components. It uses a separate microcontroller (like the Pro Micro or Elite C) to enable flexibility in connectivity and to further simplify the soldering experience (no more tricksy USB ports).
Make example for this keyboard (after setting up your build environment):
make sthlmkb/litl:default
