What is needed to get the module up and running:
  We have a   kit   that  contains most of what you need. 
Or here they are  separate:
Power supply 8-24 volt (batteries or wall plug)
Battery Holder
9v battery clip
9v battery holder
Wall plug
Button or Switch 
Contact Switch with leads
Toggle Switch
MicroUSB to USB cable or microSD/TF card
microSD card

MicroSD USB reader
Different things that can be done with this module
No programming is needed, all you need to do is drag and drop the sound files onto the device or a microSD card and apply power.
Can be used as a cheap MP3 player
Great for DIY enthusiasts
Amazing for  one-off projects and or prototypes
An easy and powerful sound module that can work with any computer.
 
Configuration files for advanced features
(download then rename the file to "read.cfg" before copying to the microSD card. Also, make sure your file is named read.cfg and not read.cfg.txt, etc.)
Pulse interruptible one-on-one playback: (This is the default mode) In this mode, a single negative pulse will start playback. It is possible to interrupt the playback by pressing the same button used to activate it. Once playback is interrupted, it will automatically restart the audio file immediately. It’s also possible to interrupt the playback by pressing any of the other 3 buttons. Once playback is interrupted, it will automatically start the sound that is associated with the button pressed.
Level hold loop playback: In this mode, the negative pulse must be held/maintained to the sound module trigger for the audio file to complete. The audio file will only playback while the button, or negative pulse, is held/maintained during playback. Once the button is held, or the negative pulse, is removed, the playback will be stopped/canceled. If the button is kept holding, when the playback of the audio file is finished, it will start to play it repeatedly (loop playback). For example, use a toggle switch to keep playing an audio file for as long as the switch is toggled to the ON position.
Pulse non-interruptible one-on-one playback: In this mode, a single negative pulse will start playback. It's not possible to interrupt the playback by pressing the same button or the other buttons. Once an audio file is triggered, the audio file will not be able to be interrupted/canceled during playback. The playback will only end when the audio file has played its entirety.
Standard MP3 key mode playback: In this mode, the buttons K1, K2, K3andK4 will function as Previous, Next, Play/pause, and Stop respectively. In this case, not like the other 3 trigger modes above, more than 4 audio files can be placed.

How to format your microSD/TF card if your microSD/TF card is currently not formatted with a supported file system

(These same steps can be used to reformat the internal memory of the sound module itself)

Formatting the SD card deletes all the data off of the card!

For Windows:

 
1: Bring up Desktop View

If you are not already in Desktop View, bring up Desktop View by pressing the Windows key + D on your keyboard.

2: Open 'Computer'

Open up the 'Computer' window by pressing Windows key + E on your keyboard.

PLEASE NOTE: Save all the files from your SD card that you want to keep to your computer before following steps 3 and 4 below.   Formatting the SD card deletes all the data off of the card!

3: Display right-click options

Your SD card should be displayed in the 'Devices with Removable Storage' section.  Right-click on your SD card to bring up the right-click menu options.  Select Format.

4: Format the SD card

  1. In the format window make sure that the correct File System is selected.  It should be set to FAT32 for 32GB SD cards and EXFAT for 64GB SD cards.
  2. Select Quick Format.
  3. Click Start.
  4. Once the formatting is complete, you can close the window.

Congratulations!  You have formatted your SD card.

For Mac:

    Formatting the SD card deletes all the data off of the card!

  1. Connect the SD card to your computer by using an external card reader.  Save all the files from your SD card that you want to keep to your computer before moving to step 2.  Formatting the SD card deletes all the data off of the card!
  2. Note – If you’re using a Micro SD card, please insert the Micro SD card into the SD card adapter that came with the card.  Connect the SD card adapter to your computer by using an external card reader.
  3. Also note – Mac OS 10.6.5 or earlier does not support exFAT format, which most 64 GB SD cards are formatted to.  This means that you won't be able to format or use exFAT card on your computer.  In this case, we'd recommend either upgrading your OS to 10.6.6 or later, or using an SD card that's already formatted to MS-DOS (FAT) or FAT32 to complete the below steps.
  4. Open Disk Utility.  To do this, click on the magnifying glass in the top-right corner of your computer screen.  Type “disk utility” in the search box that opens, then click on the “Disk Utility” Application that comes up.
  5. Find the SD card in the left side of the window.  It’ll be named something like NO NAME or UNTITLED.
  6. Click the ERASE tab in the middle of the window.
  7. Next, click on the “Format” dropdown menu.  Select “MS-DOS (FAT)” if the card is 32 GB or smaller.  If it’s a 64GB card, please select “ExFAT”.
  8. A message will appear asking, “Are you sure you want to erase the partition “[YOUR SD CARD NAME]?”  Click “Erase”. Now the computer will delete the contents of your SD card and format it.  You’re all done.
You are now ready to copy your MP3 files and configuration file to your SD card.
