To view the full filename make sure that "Hide extensions for known file types" is unchecked under "folder options"

Q1: I changed the configuration file to a new trigger mode. The default trigger mode is still used, instead of the new trigger mode.

A1: Make sure your computer is not set to hide the file extensions. Your file is incorrectly named "read.cfg.txt" instead of "read.cfg". Uncheck "hide extensions for known file types" under "folder options" and rename your config file to "read.cfg"

Q2: When I apply power to the module, WITH the microSD card already inserted, the configuration file (read.cfg) stored in the onboard flash memory is used, instead of the read.cfg file on the microSD card.

A2: Take the onboard read.cfg file offline by renaming it to a different name. Now the read.cfg file on the microSD card takes precedence and sets the correct mode. If it still doesn't work, put your read.cfg file on the onboard flash memory instead of the microSD card.

Q4: How do I adjust the volume of the board?

A4: All you need is a small star point screwdriver. The onboard potentiometer used to adjust the volume is the small blue square just next to the headphone jack. Turn clockwise to increase volume. Turn anticlockwise to decrease volume.

Q5: I don't have a 10W speaker on hand, so can I use a smaller speaker like 3W or 5W instead?

A5: You can, but you need to adjust the sound volume to a moderate or even lower setting to protect the speaker from damage caused by the powerful driving from the amplifier of the module.

Q8: What bitrate must the MP3 file be?

A8: The module supports bit rates of 32 Kbps, 64 Kbps, 96 Kbps, 128 Kbps, 256 Kbps and 320Kbps for MP3 files. Other bit rates for MP3 files could cause problems with playback.

Q9: What sampling rate must the .WAV file be?

A9: The module supports sampling rates of 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 or 48 KHz for .WAV files. Other sample rates for .WAV files could cause problems with playback.

Q10: I used an Apple Mac to copy the 4 sound files to the MicroSD card or onboard flash memory. Now only 3 (or less) of the 4 buttons play a sound when activated

A10: We found that some versions of the MacBook hide some of the files when they are copied to the microSD card or onboard flash memory. The solution is to reformat the microSD card or onboard flash memory, using a Windows computer and then copy the sound files to the microSD card or onboard flash memory using a Windows computer.

Q11: My computer isn't recognizing the board when I plug it into my computer

A11: Some micro USB cords can only transport power through them, so it is important to make sure the cable can transfer both power and data. In other words, some cables are only good to charge devices, but cannot communicate with them. First thing to do is test if the cable can not only charge, but also communicate with other devices such as a phone, if not try a different cable.

Q12: The .wav file has an audible "click" when finished playing on the module. However, there is no "click" when I listen to the file on my computer.

A12: We converted the frequency of the files from 22.05KHz to 44.1kHz and the "click" disappeared. The "click" also disappeared when we converted the files from .wav to .mp3 format.

Q13: The sound files that I put onto my device won't play when using a Mac to put the sounds onto the device.

A13: Please see this link that a customer wrote up about a past sound module that they used and that they used the same information to get this version to work. Here Is a link to the article as well as the software that he mentions
