Sound Module Button Control Music Voice Player Programmable Talk Chip Musical 8MB MP3 WAV USB Downloadable with AA Battery Box + USB Cable for DIY Audio Cards Christmas Creative Gift

Hint:1. Unplug the USB cable before attempting to play audio file. It won’t play if the cable is attached.2. I was able to get 117 kbps, 128 kbps and 320 kbps (default file) to play. Other rates will probably work but I didn’t try any others.I am a retired electrical engineer and needed a small module to play a small MP3 file. This module package seemed reasonably priced for what you get. The actual circuit board, switch and speaker were wrapped in pink anti-static bubble wrap. This was placed in a standard plastic zippered bag along with a battery case and USB cable. For ESD purposes it seemed adequate, but not great.My opinion is that the overall quality of this module package is very good. The circuit board was made using modern surface mount and machine soldering. The only thing that was a hand operation is the attachment of wires for the external pieces which is a normal process. Hot melt glue is used to reinforce the external connections, which is a nice precautionary measure taken for enhanced reliability.The switch and USB cable are way better than I expected. The switch is large and has a nice tactile feel as it snaps through center. The USB cable felt very secure when it was plugged into the circuit board.The best part of all this is that it actually worked on the first try! Attach the battery pack and be sure that both the pack and circuit board have their switches turned on. Press the button and the default song plays…….yeah. Plug in the USB cable and on Windows 10 - 64 bit home edition a new drive appeared in the File Explorer. Be sure to delete the default file and copy the desired file in its place. Be sure to unplug the USB cable before pressing the switch. That’s all there is to it. I haven’t tried triggering it with an external signal yet but will try later.The speaker has absolutely no bass, as would be expected for such a small speaker in no cabinet. I bet it would sound much better if it were placed in a small sealed box. Or, tap off the speaker signal and feed it into an external amp and use some decent speakers. That’s my plan.You don’t need to be an electrical engineer to use this.

The media could not be loaded. Adding my own MP3 audio file was really easy. I also like how this device can work with different voltages. I had a little chip that reduces 12 volts to 3.3 volts and that is working fine through the 3.7 volt input connections. I’m using this instead of a warning buzzer. Now the warning is an audio message. This makes it easy to have your electronic devices talk to you.Update. I bought another one to add sound to a model railroad crossing signal. I added a video. I hope you can hear the sound. I downloaded the audio from you tube and copied it to the chip.

Easy DIY melody box. Would’ve been better if thr USB port could be used for powering the item. I instead had to cannibalize an old USB cord and solder it onto the board. Still, not terrible.

I bought these for dIY Halloween props. They are easy to figure out and add sounds but they are not very loud at all. Would not work very well unless you have super sonic hearing.

Setting up the product is a little interesting, but it worked. You have to reformat it if it does not work the first time. You need a small screwdriver to change the volume but that's alright. The sound quality is pretty much what I would expect a speaker that size to have. Overall, it works well, has decent volume, and is fairly simple to use.

The media could not be loaded. It can be controlled with Arduino pwm pins . All needs to be done is to remove the push button which has two wires and have one connected to the Arduino Ground and the other to one of its pwm pins u can check the back of the board to identify the GND and PL (pl is the one that connects to pwm) . I was also able to power it with arduino's 3.3 pin.

Perfect

After giving this thing a fair shot I am done. I put the wires together (spent $ on tool to do this), I ordered two different cables to get one to fit the little micro-B 5 pin port (more time and $$), I spent time trying to get my Apple computer to access that drive, I even had my granddaughter go through it all again with me as I figured it was just me. This drive will not connect to my Apple computer, even though the directions state it does. All this took a long time for me and now it is too late to return, and I have 'altered' the product by doing step one.
