Description

This is David Hansel’s Speech Processor expansion board for the 26-pin bus. You can read more about this board at David’s Github.

This is a bare board, no components are included. This is not something I normally stock. When these are sold, they will not be restocked.

The photo of the completed board is the one I built for my Arduino Experimenter. It works great, just make sure you buy a *genuine* General Instruments SP0256-AL2 speech processor. They typically run $50+. Do not buy the $6 fakes on eBay, they will not work.
