Note: If there is no config file on the memory/micro SD card, the board will always works with the mode “0” by default.
2.2. How to create a config file
Users can create a config file without or with volume setting. The volume potentiometer on the board controls the
speaker output only, so if some users want to adjust volume from the 3.5mm audio jack output, it’s necessary to
create a config file with volume setting, otherwise a config file without volume setting is enough. By the way, in the
same time the speaker output is also subject to the volume setting in the config file.
2.2.1. Create a config file without volume setting
1). Firstly create a new text file on computer (desktop or somewhere else).
2). Open it and enter a number (mode) you need. Suppose you need mode “1”, just enter “1”. See below.
Number in Config File
Corresponding Trigger Mode

Short press the button to start playing, and during playing, if you press the button again, the playback
will be interruptible and it will play from the beginning.

Press the button and hold to start playing repeatedly, and when the button is released the board
stops playing.

Short press the button to start playing, and during playing, if you press the button again, the playback
will be NOT interruptible.

In this mode, K1 works as Next, K2 Previous, K3 Play/Pause, K4 Stop, K5 Volume Up, K6 Volume
Down, K7 Random playback (it plays a sound randomly after each triggering).
Special function: When K1 is short-circuited to GND first and use this mode in the config file and
once power is applied, the board is able to play a sound in a loop or play multiple sounds one by one
in a loop until power is off.
4
In this mode, sound file 000.mp3 will play in a loop when power is applied. Any button from K1 to K7
(associated 001.mp3 to 007.mp3) can interrupt it and switch to play the associated sound file. Once
the associated sound file finishes the playback, sound file 000.mp3 will continue to play in a loop.
5
Each button from K1 to K7 have their associated folders from 01 to 07 respectively. Each folder can
store multiple files (for example from 001.mp3 to 030.mp3). Short press the button to play sound file
001.mp3, and short press again to play the next file 002.mp3, and so on. When the last sound file
finish playing, short press again to go back to playing file 001.mp3. During playing, if you press the
button again, the playback will be interruptible and it will play next file.
6
The same as mode “5”, but during playing, the playback will be uninterruptible.
7
Each button from K1 to K7 have their associated folders from 01 to 07 respectively. Each folder can
store multiple files (for example from 001.mp3 to 030.mp3). Short press the button to play all of the
sound files in order one by one. During playing, if you press the button again, the playback will be
interruptible and it will play next file and continue to play the rest of the file. When the last sound file
finishes playback, it’ll stop.
