From the project
With the Japanese duplex matrix you can use less pins for more switches!
With the Japanese duplex matrix you can use less pins for more switches! So with that in mind we made a hub that let you make split keyboards with no microcontroller, just good old RJ45 and ethernet cables!
Rember to run git submodule update when the foostan/kbd submodule has been updated.
