Sd card for digital mp3 player serial#

On-board headphone jack, it can connect headphones or external amplifier.Ĭan be directly plugged onto the Serial MP3 Player module to use. UART TTL serial control playback mode, baud rate is 9600bps On-board speaker interface XH2.54-2P, can connect to external speakers such as 8 ohm 3-watt, 8 ohm 2 watt, 8 ohm 1 watt It is compatible with Arduino/AVR/ARM/PIC.

You can also debug the module via USB to UART module.

UART port, such as switch songs, change the volume and play mode and so on. MCU can control the MP3 playback state by sending commands to the module via There is a TF card socket on board, so you can plug the micro SD card that stores audio files. It can support 8k Hz ~ 48k Hz sampling frequency MP3 and WAV file formats. The module is a kind of simple MP3 player device which is based on a high-quality MP3 audio chip. The online docs I can find aren't technical. Like most Arduino parts it arrived alone in an envelope. I have hacked this example to the point where the extra FF's are eliminated, but still no joy in Mudville.ĭoesn't say SQUAT. This is why I was asking if anyone had PERSONAL EXPERIENCE to share. Where is the directory specified? How is song 001 specifed with only 01? Or is the 01 the directory and it just defaults to the first song? Lots of vagueness.įor(int i=0 i MP3 Command => 7E3351FFFFFFEFġ5:01:34.530 -> MP3 Command => 7E44102FFFFFFEFġ5:01:35.562 -> MP3 Command => 7E44102FFFFFFEF

thats the diag that didn't work as advertised: like this command: 7E 04 41 00 01 EF (Play with index: /01/001xxx.mp3)
