Product Details

MP3 USB Media Card Player Module with Remote Control

This module is designed to act as a DIY source to be used in conjunction with DIY power amplifiers. The minimized faceplate allows for installation in powered speakers, project boxes, automotive and marine applications... the only limit is your imagination.

This module requires +5 volts DC which is readily found on computers, devices, and power supplies with USB ports. It is recommended that you solder the wire leads from the power connector to a USB-B female connector (please see the Related Products section). This allows for the use of a USB-A to USB-B cable  for proper connection to an active USB port for power.  

A two-wire cable connector is supplied for power. Carefully connect the two-wire cable connector to the two-pin board connector aligning the placement tab with the socket notch. Identify the proper board connector by locating the +5V and GND labels on the underside of the module's circuit board. A drop or two of superglue is recommended to permanently hold the connector is place.

Drag-and-drop MP3 files (only the MP3 audio codec at 32-320 kbps is supported) from your computer onto your storage device (USB or SD Card) for playback. It is recommended that you place songs directly into the root directory of your storage device. Cutout requirement: 2-1/2" W x 1-1/4" H.

Note: The manufacturer that supplied this part has switched to a different control that no longer has the folder up/down options.

MP3 USB Media Card Player Module with Remote Control
MP3 USB Media Card Player Module with Remote Control is rated 4.2105 out of 5 by 19.
Rated 5 out of 5 by from Works exactly as advertisedBought this to integrate into a mp3 stuffed animal toy I'm making for my nephew -- I wired it up to an LM386 and my 7805 5V regulator and bammo tunes... works flawlessly -- the wiring diagram that came with the unit is especially useful and greatly appreciated! A+++ guys! :)

Rated 5 out of 5 by from Works Great!This unit does exactly what the ad claims. The complaints of poor documentation is justified - even worse, the unit has changed and the documentation has not been updated. The audio output is via a 4-Pin plug and there are 2 spots that it will fit. I tried the wrong one first, but it did not seem to harm the unit - when I tried to other it worked fine. If you need a card player like this there does not seem to be much else available. This reader does exactly what I need.

Rated 4 out of 5 by from Great module, needs better documentationThis is the second of these mp3 modules I have purchased. They are a terrific value and the sound is really good for the price.The only problem I have is when the remote on the first unit quit working unexpectedly, no replacement remote is available for purchase. Without much more in-depth documentation, no repair or DIY rescue project is possible.If either separate remotes or better docs were available, I would be able to give the stellar rating that this unit truly deserves.

Rated 5 out of 5 by from Perfect for a museum applicationThis player automatically plays and loops all the files on the USB stick or SD card as soon as you supply power. The pause at the loop point is short (maybe 1/4 sec) and silent (no pops or digital noise). When you remove power it shuts down safely and starts at the beginning when you turn the power back on. In this usage scenario you don't need the front panel buttons or remote. "It just works."These are exactly the features I needed for unattended looping playback in a museum context. This item is cheap and the sound quality withstands critical listening (no digital interference during playback, flat frequency response, no noticeable background hiss).In case you're wondering, the line output is not suitable for driving headphones. (Low output, rolled-off bass) Add a headphone amp like the tiny Fiio E3 (230-108) and you get full sound with plenty of volume.

Rated 5 out of 5 by from Works, + cheap/easy caseI bought one of these units to use as a portable player and not worry about a more expensive phone or MP3 player. Functionality is like everyone else has described; I've noticed that if you copy over a directory tree with multiple folders, the player appears to step through the folders and music files in alphabetical order.I tried mounting it in a Radio Shack project box, but was having trouble cutting the mounting hole. On a whim, I visited the local big box home improvement store and took a look at electrical cover plates & single-gang boxes. Turns out the player is almost a perfect fit in a 1-gang cover plate for GFI outlets or large slide dimmer switches, and fits well inside 1-gang junction boxes. Much easier to drill mounting holes (min of 2 on the diagonal) to keep the player in place. Depending on what tools you have, get a nylon ("unbreakable") cover plate, or a metal one. The cheaper hard plastic plates shatter too easily.The box has enough space to hold batteries, a voltage regulator, and plugs for external power and audio out. For now, I am using an old 5V phone charger with a coaxial plug.Because it fits well in a box designed for wall installation, you could have a basic MP3 player built into a wall in the same space required for an outlet or light switch.

Rated 5 out of 5 by from Fantastic!I've been looking for sometime for an mp3 player that I could load with music, connect it to my car, and forget it. THIS IS IT! I wired in a 5V regulator, added a 12V cord and added a 3.5mm stereo plug and housed it in a small box from Radio Shack. I have power and aux input in my center counsel. I put my player in there and never have to think about turning a player on. It just starts playing when I start the car. It's great that the last song played is the first song played when I start the car again. The only feature that is missing is a display, but the way i use it...I don't really care. :)

Can this unit play songs randomly?

I don't see in the details, but was wondering if this device can play songs randomly from the USB or memory cards, or does it always play songs in order?
Asked by: TomZ
This product does not have a "shuffle" or random feature. You can skip forward and back through your songs, but there is no feature for mixing them up in any way.

What is the order in which it plays songs?

In other words, is it alphabetically (file name), date/time, etc.I loaded up a USB stick with a few CDs worth of music and can't seem to get them to play in the correct order.Other than that, it does just what I want. Feeds a little 2020+.
Asked by: Lagnar
The songs are played in the order they are saved on the source. If you want the songs in a particular order, you can append a number to the file names. For example: "01-songname.mp3, 02-anothersong.mp3" and so forth.

How large of an SD card will it read?

Asked by: Selmer57
At the moment I am running a 16 GB SDHC in it just fine. I would assume that it will take a 32 GB SDHC, but I don't own any at the moment to test.

Would this unit operate correctly on 4.5 - 6 V DC?

Asked by: Huck
The specifications state +5 volts DC, so I would recommend using a regulated power supply rated for that voltage.
