Gravity UART MP3 Sound Voice Module

With this new Gravity Voice Module from DFRobot, you can realize your Arduino DIY projects with music and sound effects. This module can store 8MB audio files, meaning it can record more than 200 audio files that can be specifically played with an Arduino. The most popular formats such as MP3 and WAV are supported by this MP3 player module. The storage method is as simple as using a USB stick. The audio files can be updated anytime via the USB port. Your Arduino can communicate with the module via the UART interface and play the desired audio MP3 files or simply change the volume. It is suitable for all types of projects where you want to play sound effects or MP3 with a microcontroller.

Info: You can reverse the connector cable by attaching a Dupont cable M-M 10cm to male, so you can also use it on an Arduino UNO.

Characteristics:

• Files can be copied from a PC to the sound module via the USB port
