A tiny add-on board with a four letter word association database!

It can be used together with our Arduino Library to create a fun and fascinating four letter word generator using any Arduino board.

Our null also supports it!

NOTE: The current revision (mkii) of null has built-in Four Letter Word support, and does not require this extra module. Customers with the older version 1 base board will need to add this module for Four Letter Words support.


  • Pre-assembled PCB with pre-programmed EEPROM
  • 4-pin male header

Arduino, VFD Clock / other display not included.
