Comes with 5W class D power amplifier, can directly drive 4Omega, 3~5W speakers.
UART serial port control voice broadcast function, can control playback, pause, song selection, volume addition and subtraction, etc., the largest selection of 65,535 songs, baud rate of 9600 bps.
Support IO trigger playback function, 8 IO ports trigger 8 tracks or 8 IO ports to trigger 255 tracks.
Support One_line single bus serial port control, can control playback, pause, song selection, volume addition and subtraction and other functions.
Support 3 configuration IO for up to 7 working mode selection.

Notice:
1."Key combination playback" refers to the restoration of the original high level after io0-io7 output the corresponding level, similar to the key trigger once; "Level combination playback" refers to the io0-io7 output of the corresponding level to maintain the same level.
3.The difference between "I/O combination (independent) mode 0" and "I/O combination (independent) mode 1" is that the former mode continues to play the current track until the end after releasing the level, while the latter mode immediately stops playing the track after releasing the level.
