-Lightpad keypad firmware
-======================
-Korean custom keypad designed by Duck.
-
-*Note that this is not the official firmware*
-
-
-Supported models
-----------------
-All pcb options are supported.
-
-
-Build
------
-Move to this directory then just run `make` like:
-
-    $ make -f Makefile.lufa
-
-
-Bootloader
----------
-The PCB is hardwired to run the bootloader if the key at the `top left` position is held down when connecting the keyboard.
-
-It is still possible to use Boot Magic and Command to access the bootloader though.
