DC 12V 24V 20W Voice Playback Module, High Power Sound Board MP3 Player 64Mbit Flash Storage Mono 8ohm Support MP3 WAV for Arduino Father's Day DIY

I gotta say, I was super bummed when I first tried to get this going. I used the first mini usb cable I could find (a small fan?) and nothing showed up. I thought maybe it was a Mac thing, so I tried a PC. Nothing. Then, before I turfed it, I tried a cable from a ring camera that seemed higher quality. And bam, NO NAME drive on my Mac desktop. Copied a single 10min mono audio file (00001.mp3) and now I have a soundtrack for my model train that not only starts on power up, but loops! Couldn’t be happier. :)

I used this board to build a music player to replace the annoying backup beeper on my golf cart. It does not come with any instructions, but the info is available online. The default switch setting was perfect for what I wanted. I wired a single pole, 11 position switch to select which of the songs to play when power is applied to the board. Mounted the board and switch in a box that I mounted between the seats in the cart. Used a 20W speaker mounted next to where the existing beeper is. When the Forward/Reverse switch is in reverse, the + side of the 48V battery is connected to the beeper. I used that connection for the + to the board and the - for the board tapped into the batteries so that 18 volts is applied to the board when the switch is in reverse. The board contains 8 MB of storage, enough for up to 8 minutes of songs (I edit the sound clips I use to 30-45 seconds, they will just repeat as long as power is supplied to the board). I mounted the board on the back of the selection switch making up a small aluminum bracket to attach. Works great. I change the music depending on the season - for Christmas - Grandma Got Run Over by a Reindeer is going to be my number one song!

I programed it to say "lizard" (from the tiktok videos) everytime my girlfriend uses her horn. First time doing something like this, took me hours before I realized my micro USB was not data transferable, but after that is was very simple and easy to use.... not much information comes with it but Digital Town video #113 on YouTube was very helpful. Also for anyone else who's new to this. The triggers use negative to activate, not positive.

Great amp & sound, and everything works perfectly. Uninstalled the trimpot and installed a pot on the box. Perfect to use with a PLC. Just wish it had more memory to store larger mp3 files (8 of them). Revision: Dip switch settings explanations for IO modes not clear. Unless the trigger connection is removed, all of the 4 IO modes continually play the selected sound; no dip switch setting to play the selected sound once.

My requirements were simple. Power it on and have it play the first and only song in Flash Memory. I couldn't verify from internet info whether this is what happens. Fortunately. Just apply power to my unit, (with the DIP switches in the MP3 mode) and music starts immediately. Just what I needed. When the play wraps from the last song back to the first, there is a six second message in Chinese. I have no idea what it says.
