The Sound Board has a lot of amazing features that make it the easiest thing ever:
No Arduino or other microcontroller required! It is completely stand-alone, just needs a 3 to 5.5VDC battery
Small - only 1.9" x 0.85"
Built in storage - yep! you don't even need an SD card, there's 2MB or 16MB of storage on the board itself, so
