Adafruit Audio FX Sound Board 2x2W Amp - WAVOGG Trigger -16MB
The Adafruit Audio FX Sound Board + 2x2W Amp WAV/OGG Trigger-16MB has impressive customer reviews for its versatility, ease of use, and reliability. Users can store numerous sound effects as long as the files fit in the 16MB memory. The built-in amplifier is both space-saving and reduces wiring complexity, and there are pins on this device for a line-level audio output if you want to connect it to a powerful external amplifier. An important note is that if the board is connected to a computer and mounted as a USB storage device, audio will not play back. The device can still be powered by a USB charger, and files will still play back fine. Additionally, a typical PIR alarm motion sensor will need to reverse the logic or use a "normally open" connection if it exists on your motion sensor. The customer reviews share that the sound quality may be better with the cheaper version with audio line out (not with onboard amp) and adding a separate amplifier to get good sound quality. One user wired a AA battery pack, a power switch, volume up/down buttons, and two arcade buttons that play 8 tracks of audio to the device and it has been going strong for over a year. However, some users had issues with the computer no longer reading the storage inside the board, and there were comments on it not being very loud. One user noted that there is a short pause between the end of the track playback and "restarting" at the beginning, even if playback was set to loop. **
