HS-S51-L Mini MP3 Adapter Board

1. Introduction

Use the Mini MP3 module to play MP3 songs from a storage card, it is necessary to add a speaker and connect the Mini MP3 module separately, and then connect the Mini MP3 module to the main control board such as Arduino via DuPont wires to achieve the MP3 playback function.Our product has integrated a speaker and is equipped with two rows of 8P single-row female sockets, which can directly insert the Mini MP3 module (the direction of the storage card slot and the 4P terminal port are the same), and is compatible with LEGO bricks. It can be connected to the main control board such as Arduino through the 4P terminal to DuPont wires for program design, thereby realizing simple MP3 playback function.
