A compact and inexpensive MP3 module that can directly connect with speakers.

A module with power supply battery, loudspeaker, and button can be used alone or by serial port control.

The module perfectly integrates the decoding of MP3, WAV and WMA.

The software support TF card driver, can also support FAT16 and FAT32 file system.

Through simple instructions, it can complete the function of playing designated music without complicated bottom operation.

Easy to use, stable and reliable.

Use 5050 full color super bright LED

With current limiting resistor to prevent burning out the LED

Can be accessed by a variety of micro-controllers

Can be directly inserted in the Arduino motherboard

The power meter, the module does not work.

Each type of bluetooth module can be installed commonly, such as HC05/06/07 / BC04 or other compatible bluetooth module per definition.

With clear key, it can be support pin of the module (e.g., host HC05/06/07)

Set EN can make pin, suspended or high levels, the normal work of the module; Closes as earthing module power (closed current < 20ua) reduce power consumption.

Note: connection BC04 default for hardware settings and from the pattern, if you need to modify for the software settings should be from 3.3V to PIO4 fly line.
