When using the mini mp3 module to play MP3 songs on the memory card, you need to add a speaker separately to connect with the mini mp3 module. The mini mp3 module can realize the MP3 playback function only by connecting it with the main control board such as DuPont line and Arduino. This conversion board has been combined with 0.5W, 23x8mm in-line passive speakers, and is equipped with two rows of 8p single row female seats, which can directly insert the mini mp3 module (the slot direction of the memory card is the same as that of the 4P row pin). Through the 4P row pin, it is connected with DuPont line and Arduino and other main control boards for program design, and simple MP3 playback function can be realized.
