Better voice quality
It has two sampling rate options; 60kHz, and 80kHz. The audio quality is better when you select 80kHz, but you can only record 60 seconds of audio.
If you select 60kHz via the sampling jumper , the audio isn't as good, but you can record 75 seconds total. At 60kHz the audio quality is still decent, but at 80kHz, the audio quality is very nice! This board requires 5v to operate. There is a 5mm jack in case you wanted to use a wall transformer, but there is also a two pin header that you can connect your 5v supply to easily. Otherwise, you can solder your supply wires under the board on the solder side.
There is an on board microphone, and you can connect a small speaker directly to the white SP+/SP-
You can easily interface an audio amplifier to the speaker outputs. You can also use the audio output jumper for this. Right beside the power header, there is a two pin header labelled "AUOUT", which stands for audio output. If you connect the speaker to this header, you will be able to head an un-
There are 7 buttons on board.
RESET: Resets the programmed settings, but does not delete the audio that you've recorded.
VOL: Lessens the output volume. Press the RESET button to reset the volume settings.
