## Questions & Answers

**Q: Hello, can i please attach this to 5v dc power, connect to speaker and have it automatically play mp3 files off micro sd chip?  does it need amp**
A: The speaker output is just a mono output intended for monitoring. The main audio output is the audio output jack provides a headphone-level line output. So to play it through speakers, you would need an amplifier module.

**Q: Can you power with a 12v power supply?**
A: no ... i use a step down buck transformer (relatively inexpensive) to step down from 12v to 4 to 5v DC. 
12v DC will burn out the board.

**Q: will it loop without keep pressing the button?**
A: Yes, once you press the repeat button, it will continue looping indefinitely, until you press another button or power it off.

**Q: How do the secondary action for each button work? For example, how do you turn the volume up?**
A: The buttons are each marked on the board itself example volume up V++ volume down is v--

## Customer Reviews

### ⭐⭐⭐⭐⭐ This is a perfect solution for themed attraction builders.
*by C***Y on May 5, 2024*

Creating public spaces with themed audio tracks is a breeze using these MP3 players. All you need is a mini usb cable and a charging block to power the device and a male mini phono jack wired to an amplifier and speakers to complete the sound system. Load an audio file on a memory card and put it in the card reader. The stereo output is good. Jungle sounds in one section the attraction and a haunted theme in another. Perfect.

### ⭐⭐⭐⭐ It works.  Gets hot.
*by K***R on October 19, 2024*

It works. It gets hot, so I pasted a couple heatsinks to the chips and that helped. I’m still trying to figure out how to make a decent enclosure for it, but it works well for my audio testing probe. I only use it to play test tones.

### ⭐⭐⭐⭐⭐ Convenient for certain applications
*by F***. on July 17, 2023*

One of these I use to play a single 12-hour MP3 with continuous fan noise, was using a website with an RPi connected through bluetooth and just hooking this up to some speakers instead is far more reliable. Also handy for synth DIY and electronics work, a lot cheaper than blowing up a cell phone or fancier MP3 player. Only real complaint is the red blinking LED is too bright.
