Sampling rate: 8,11.025,12,16,22.05,24,32,44.1,48Khz. Fully supports FAT16 / FAT32 file system, maximum support 16GTF card. DC5V power supply, with two sets of interfaces. Volume adjustable, simple knob adjustment method. Low trigger to trigger. Support 0 ~ 2W, 4 ~ 8 ohm speaker load. With a standard 3.5 audio interface, support for audio, amplifier connection. Application: SCM voice broadcast applications, factories, warehouses, corridor safety warning, intelligent car, electronic design applications, electrical and mechanical equipment, electronic application products alarm warnings, advertising, automatic broadcast regular broadcasts news, equipment operation and voice guidance, voice warnings. Touch trigger mode: Module has nine direct trigger port, this is the A1-A9 9 pin. The nine ports simultaneously correspond to 9 MP3, are the first the first to ninth head first, into the TF card is the first song. Trigger mode: for example A1 port, as long as a low level to A1 port to be playing the first MP3 immediately. Low voltage is 0V, GND can board to trigger. Or triggered directly by the microcontroller IO port. Encoded trigger mode: This module in addition to the direct trigger 9 MP3 functions also have 31 MP3's on-demand capabilities. But this feature requires a combination of microcontroller to complete the operation. Note: Memory Card (TF) for MP3 format is as follows: 1. Name the folder mode: Create a folder named "01" in the memory card inside. 2. MP3 audio file name format of 001 to 999 at the beginning to be named. For example: 001Jingle Bells.MP3,002White Christmas.MP3 ..... and so on.
