Review on Adafruit Mini Sound Board - WAV/OGG Trigger - 2MB Flash Memory [ADA2342] by Klassic Duncan

This board is really well designed and very easy to use. I like that you can use it as a flash drive to manage files and you can tell the board how it works by the way the sound files are named. Although it's listed to operate from 3 to 5.5 volts, I recommend using it with a 5 volt power supply. The board I received only intermittently allowed audio to be triggered when powered by a 3.3 volt power supply. With 5 volts I never had a problem with the board. I am using it with a DROK Super Small 3W+3W DC 5V audio amplifier to play a message when the emergency stop button is pressed in a commercial spa.
