Volume is adjustable using a small potentiometer on the circuit board.【8M MEMORY】Connect with your computer by a micro USB DATA Cable. A micro USB charging cable is insufficient and will not work.It is recognized by computer as a USB drive, just like a MP3 player, and you're free to add any MP3 audio file to the internal 8M storage.【EASY TO PLAY WITH ON】Install it in your project/gift, and then push the on. Your music which you put in it will be played once and automatically stop when the song finishes.【PROGRAMMABLE SOUND MODULE】Provide more possibilities to develop a module completely fit for your own project. You can select different trigger mode (on/TTL trigger) by connecting with different soldering pads.【VOLUME CONTROL】Volume is adjustable,Power supply voltage is 4.5-5V,Recommend to use 3.7V lithium battery (Batteries are NOT included),Output 0.5-1W.The USB cable is used to update music, not to play. When playing music, you need to connect the battery with the red and black wires.Control modeIn the table,‘0' means having 3.3K resistor; '1' means without 3.3K resistor.You can see that there are 3 resistors on the board, so the default mode is 000 (It will play the music once you press the on. If you press the on again during playing, it will stop immediately)You can change to other mode by removing the resistor on the board. For example, if you want to set 001 (Under this mode, you need to hold down the on to play the music. It will stop once you release the on.), you need to remove the third resistor that marked C on the board. To remove the resistor, you need a soldering iron to melt the solder and take the resistor away. It is a little difficult if you are not good at soldering so we recommend you to use 000 default mode.Power-ON-Play modeIt will enter Power-ON-Play mode if short circuit between two pads of on. That is to say, it will play voice immediately when power on.Instructions1.Connect 4.5V~5V non-rechargeable battery power;2.Press the on, and you will hear a test music which is a Chinese song. Press the on during playback, then it will stop playing immediately.3.Connect the module to computer by USB cable; SUPPORT WINDOWS ONLY4.It is recognized by computer as a USB drive, just like a MP3 player, and you're free to add any MP3/WAV audio file to the internal storage as as it doesn't go over the 8MB limit;5.Do not forget to delete the default audio file;6.Repeat Step 2 to see if the module work well. Adjust the volume to a suitable degree.7.PLEASE NOTE: The USB cable is used to update music, not to play. When playing music, you need to connect the battery with the red and black wires.------------------------------------------------Frequently Asked Question-------------------------------------------------------Q: Why the product came with NO INSTRUCTIONS?A: We provide PDF instruction on this page. Please download it at:http://attach01.oss-us-west-1.aliyuncs.com/IC/DIY-Manual/10060.pdfQ: Can I power the board with a USB battery stick? I used a power stick as power supply, the file will not play.A: The micro-USB connector is on the circuit board for adding or removing sound files.?The micro-USB connector is not for powering the device.?Please wire a 3.7V Lithium Ion battery to the red/black wires. The red wire is positive and the black is negative.Q: Why my Windows computer can't recognize the module?A: Please note that a?micro USB DATA Cable?needs to be used to interface with this sound module. A micro USB charging cable is insufficient and will not work.Q: I want to confirm that I can replace the speaker with a 1/8" audio jack and plug into a power speaker?A: I am not sure if that it's feasible because the module and the audio jack output different audio signal. It may not work after transforming the audio signal, but you can have a try.Q: Can I connect to a self-powered speaker?A: Yes. But it should be 8ohm 0.5W speaker.Q: I was able to put an mp3 file on it by using a microusb cable, but every attempt I've done feed the device with power hasn't produced any song.A: The working voltage of the sound module is 4.5-5V. We recommend to use 3.7V lithium battery. I can see on the photo you sent me that you use a 9V battery, which is nearly 2 times of the acceptable voltage. It is very likely that the module has been burned out. Please try with a 3.7 lithium battery.
