Merging the Adafruit FX soundboard and the Arduino Pro Mini

Hello all!

I wanted to know if it was possible to merge the components of each of the boards into one board. I know both Eagle files on available online which is super convenient, but I am concerned about the programming side of things since I am not sure if there is some preprogramming of the FX board done by Adafruit

Here is the adafruit pinout info page for reference: Pinouts | Adafruit Audio FX Sound Board | Adafruit Learning System

Your best bet would be to check with Adafruit. Those VLSI chips can be programmed so it wouldn't surprise me if Adafruit had loaded their own firmware onto them.
