3>.24-bit DAC output, dynamic range support 90dB, SNR support 85dB.
4>.Fully support the FAT16/FAT32 file system, with the maximum support 32GB TF card and 32GB U-disk.
5>.Support UART serial port control voice broadcast function, can control playback, pause, selections, turn up and down volume and other functions, the largest selection of 65535 tracks.The baud rate is 9600 bit/s.
6>.Support IO trigger function, 8 IO ports can trigger 8 musics or 8 IO combinations to trigger 255 songs.
7>.Support One_line single bus serial port control, which can control playback, pause, selection, turn up and down volume and other functions.
8>.Support 3 configuration IO for mode selection.

Function:
1>.It cannot be used alone, it can only be used together with XY-V17B;
2>.It combines the peripheral circuits required by XY-V17B to facilitate the debugging and use of XY-V17B;
3>.Support Micro USB download for TF card;
4>.Support U-disk and 3.5mm audio input;
5>.Built in 5W amplifier;
6>.Support IO0~IO7 external extension trigger.

Use steps:
1>.Install XY-V17B on module XY-V17D;
2>.Connect to 4ohm~8ohm speaker;(Speaker is not include in package!)
3>.Connect working voltage;
4>.Set work mode by jump cap CON1~CON3;
5>.Test by button on module;

Mode configuration and pin function:

Note:
1>. "key combination play" : Return to the original high level after the corresponding level from I/O0-I/O7 output, similar to the key triggered once.Similar instantaneous switch.
2>. "Level combination play" :The trigger signal remains the same, similar to a self-locking switch.
3>.The difference between “I/O Integrated/Independent Mode 0” and “I/O Integrated/Independent Mode 1” :Mode 0 will continue playing the current song to the end after release level .Mode 1 will stop playing immediately after release level.

Mode operation instruction:
1>. I/O integrated mode 0(Key combination playing).
It will stop playing current song to the end after I/O0-7 release input signal(return to high) at 'I/O Integrated Mode';It will playing new song when get new input signal during playing and stop after end of song;It will play repeatedly if keep input;Busy pin will output valid signal(High) during playing.
Note: the song must be named for 5bit.
Music control:

2>. I/O integrated mode 1(Level combination playing)
It will keep playing current song when get trigger signal.It will stop playing immediately after release level.Busy pin will output valid signal(High) during playing.Note: the song must be named for 5bit.
Music control:

3>. I/O independent mode 0((Key independent controlling)
I/O0-I/O7 independently controls 8 songs.It will stop playing current song to the end after I/O0-7 release input signal(return to high);It will playing new song when get new input signal during playing and stop after end of song;It will play repeatedly if keep input;Busy pin will output valid signal(High) during playing.
Note: the song must be named for 5bit.

4>. One_line Single bus serial port mode

Waveform:



Command format:

Note: "selection" and "interplay" are played according to the track name, for example, the track is named "00123. Mp3", and the selected data is "0x01", "0x02" "0x03" "0x0B", and the selection is completed.

Package:
1>.1pcs XY-V17D UART Voice Controller;
