Overview
DFPlayer mini MP3 player is a small and low cost MP3 module player with a simplified output directly to the speaker.
The module can be used as a standalone module with attached battery, speaker and push buttons or used in combination with an Arduino UNO or any other with RX/TX capabilities.
It perfectly integrates hard decoding module which supports common audio formats such as MP3, WAV and WMA.
Besides, it also supports TF card with FAT16, FAT32 file system. Through a simple serial port, users can play the designated music without any other tedious underlying operations.

A few weeks ago, an announcement was posted on the Arduino Forum mentioning new improvements on the software side of the Arduino/Genuino 101. With this release, the board--which was developed in collaboration with Intel--is reaching its full potential, with not only better code generation but unlocking useful features to make your sketches even more interactive as well. You can easily upgrade the core using the Arduino IDE’s Board Manager (pictured below), while Arduino Create users will be automatically updated, so no action is required--the cool thing about the cloud! In more detail: The GCC compiler has been updated to support hardware extensions to the ARC EM core in the Intel® Curie™ module. This provides significant improvements in floating point operations, bit shifting, and other operations to enhance Sketch performance. The Arduino/Genuino 101 platform offers 2MB Flash storage onboard, which is now enabled for user sketches. An experimental driver has been implemented to enable the I2S interface via the CurieI2S library. Connecting the I2S bus to an external DAC (digital to analog converter) allows users to play high-quality music (HiFi). Other improvements and bug fixes: Motion Sensor: Several sample sketches, like MotionDetection, have been implemented to demonstrate the application of the IMU data Bluetooth LE: Several new examples for BLE peripheral library added IMU: Correct motion detection setting implemented Library CurieTimerOne APIs are now compatible with the TimerOne library For comprehensive release notes refer to the Intel Open Source Technology Center on GitHub.
