DFRobot Gravity UART MP3 Sound Voice Module

With this new Gravity Voice Module from DFRobot, you can bring music and sound effects to your Arduino projects. This module can store 8MB of audio files, meaning it can hold over 200 audio files that can be played back selectively with an Arduino. Common formats such as MP3 and WAV are supported by this MP3 player module. The storage method is as simple as using a USB stick, and audio files can be updated at any time via the USB port. Your Arduino can communicate with the module through the UART interface to play the desired MP3 files or simply adjust the volume. It is suitable for all types of projects where you want to play sound effects or MP3s with a microcontroller.

Info: You can reverse the connection cable by plugging in a 10cm male-to-male Dupont cable, allowing you to use it with an Arduino UNO as well.
