PUI API-4260-LW150-2-R Programmable Audio Indicator
Did you ever make a project and wanted to output a sound that was more than just a beep? Or maybe you wanted to play a long song on repeat, such as an audio alert for when something is not working on a factory, or just to annoy your friends, your choice. An Audio Programmable Indicator is basically what you need, and the PUI API-4260-LW150-2-R might just be your best choice if you are out to get one!
But what does differentiate this product from other API’s? First off, it is extremely easy to use, even easier than normal. You can plug it in via USB to any computer (as it is recognized as a USB device), drag and drop an MP3 file, and you are set! Then it is ready to be integrated with your projects. All you have to do is power it and it will play your song on repeat when you power it.
But what is going on in there? Well, if you open it, and you can take a look at this process in the Adafruit’s video where they actually tear it down, there is a buck converter, along with a 4MB SPI flash chip and followed by an interesting, cheap IC that can basically only play MP3. From that point on, there is only the amplifier circuit and the speaker itself, aside from the USB port.
More about the specs:
- 12 V rated voltage, range from 7 to 24 V
- 350mA of current at rated voltage
- Repeating tone/pulse
- ABS housing material
- Easy drag and drop file transfer on nearly any computer
- 150 mm lead wires and mounting flanges for easy integration
- Wide frequency response (100 Hz to 20 kHz)
- Mini USB-B port
What is so cool about it is its simplicity. How many projects have you just wanted to play a sound and this is probably the simplest way possible that does not suck! It can be used on projects where you need to alert, or even assist someone with audio. Even though the API is a simple product, there is a lot of utility in this little guy!
Lastly, let us talk about pricing: how much? Actually, is not a lot. This API is available on Digikey for $21.93. Now, could you DIY this for cheaper? Probably, but what you are getting, the simplicity in such a solid package may be enough to make you forget about the price. What do you think, will you pick it up? Where would you apply it?
