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. SD capacity 32GB. 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 4.2083 out of 5 by 24.
Rated 5 out of 5 by from For the price, you can't beat it!I have been working with this unit for more than 2 months on the bench, and it is surprisingly good quality for such a low price.Pros: Better fidelity, lower distortion than many bargain basement MP3 players I have tested; remote that works reliably to at least 2 meters (have not tested beyond this distance as of this writing), great output level (will drive most any amp to it's full output), and a good pair with one of those class T amps. As another reviewer has pointed out, this unit when powered off will return to the beginning of the song you were previously on prior to power being removed. This holds true even with the SD card being pulled from the slot and reinserted with the power off (I haven't yet tried the USB Drive slot as of this writing). Still have yet to test max SD card data size, but works well with 1 and 2 GB cards.Cons: Quality of Power supply can be very important. Have noticed a small backgound "motorboating" oscillation that occurs with some regulators when volume is less than full up. Turns out that there is an empty capacitor slot in the MP3 module, and tech savvy types can add your own capacitor (I used 470uf), which will cut the small noise quite a bit... but, as I said before, simply using a higher quality +5VDC power supply will kill this issue - I had even good luck with an old cell phone charger wall wart - 50 cents from a garage sale. Other issue is the documentation provided isn't comprehensive enough. I accidentally plugged the audio cable into the wrong slot (was meant to be an audio Aux input of some kind), but unit worked well once the cable was relocated.Summary: I have tested 8 different modules from different manufacturers, and nothing else came close to the quality of sound, durability, ease and flexibility of use. I'm so satisfied I've ordered more of these. In my opinion, you can't go wrong, especially if you pair up with a good Parts express Class T amp and small full range speakers, you will have a nice little system that will fill the room nicely.

Rated 5 out of 5 by from I've Bought 3 So Far...These little guys are great for making projects. So far I've made 3, each one going into a project box, into which I attach a power jack and audio out connectors. These work great as MP3 decks for your stereo. I have one connected to my huge home stereo and now I can play my music all day and never have to flip a CD or change a channel, etc. The sound is clear and so far there hasn't been an MP3 it won't play, in regards to sampling rate and whatnot. I'm considering making these as gifts for friends. I'll probably buy more.

Rated 5 out of 5 by from Easy integrationI added this to a backyard stereo project and was impressed with the easy integration. It came with diagrams for where the included connecting cables go and their pin definitions. The sound is clean and operation is simple. When powered off mid-track, it will start at the beginning of that track once power is reapplied. It works as advertised.

Rated 4 out of 5 by from Create an iTunes playlistI’m glad I waited a bit to write this review. This device works exactly as advertised but I questioned the real world use of this player. With all the streaming applications out there and iTunes, at first I didn’t really see a use for this other than charging a cell phone or iPod. I buy most of my songs through iTunes and this card reader only plays mp3’s. Here’s a few steps that on how to create an mp3 playlist in iTunes and transfer them to an SD card. Open iTunes Preferences. Windows: Choose Edit > Preferences and Mac: Choose iTunes > Preferences. Click the General button, then click the Importing Settings button in the lower section of the window. From the Import Using pop-up menu, choose “mp3 encoder”. For higher quality playback, under the Setting menu choose “custom”. Under the Stereo Bit Rate menu choose “256kbps”. Hit “OK” 3 times to save changes. Next create a new playlist of the songs you want to rip to mp3 format. Select all songs in the new playlist and right click. Choose “Create mp3 version” from the menu. Once iTunes is done converting all files you can search for them. Sorting by “date created” or “mp3” works well. Once you have all the mp3 files selected copy them to you SD card and you’re in business. Now instead of having your phone plugged in or an iPod you can have all your music at the flip of a switch. I have mine paired with a DT1A amp, 5V regulator and a 4500mah lithium Ion battery. I put the mp3 player on a separate SPST switch and spliced in a 3.5mm headphone jack input.

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! :)

MP3 USB Media Card Player Module with Remote Control

I don't understand how to have both devices such as this and an amplifier share a power supply if one is 120vac and another is 5 vdc? Can someone describe in detail what parts I need and how to wire or a link online? This would help me greatly thanks.

Asked by: frenchman111
You can use a 7805 voltage regulator to bring the voltage down to 5vdc. Please review the video online for further installation and wiring instructions.

Does the unit require line of sight to the remote for the remote to operate, or can the faceplate be hidden?

Asked by: tinkertailor
This unit uses IR remote control, so line of site is required.

I'm getting constant noise I'm not sure why. I'm using a car phone charger hooked up to 24v batteries. I also tried it with a 5v adapter and there is less noise but still some. I have it hooked up to the 2x50w tda7492 amplifier 320-301

Can multiple units be synched to start at same time via hardwire connection or can one remote control multiple units at the same time?

Asked by: the beatcatcher
I have not tried to control multiple units with one remote, but believe this would work. A hard wired connection definitely would work, using the ADKEY connection to a multipole switch to the specified resistance, to ground.
