A tiny add-on board with a four letter word association database!
Use this module together with an Arduino and our Four Letter Word library to create
a Four Letter Word generator!
It can also be used with version 1 of the VFD Modular Clock to add Four Letter Word
functionality (may require firmware update). Version 2 of the VFD Modular Clock already has Four Letter Word functionality built-in, so this module is not required.
