3.Store Music

Before controlling the MP3 module to play music, you need to store songs on the memory card of the MP3 module. The following are the steps to store songs on the MP3 module:

(1)Insert the memory card into the card slot of the MP3 module.

(2)There is a USB port on the back of the MP3 player module. Use a Type-C data cable to connect the USB port of the MP3 module to the computer.

(3)After connecting the MP3 module to the computer, a new folder will pop up on the computer system disk. Place your MP3 file in the newly popped up folder. If your MP3 file is placed in the root directory of the memory card, the name of the MP3 file must start with a four-digit number, such as “0001Hero.mp3”, “0002Jingle bells.mp3”.

If you want to create a new folder in the root directory of the memory card, the folder name should start with a two-digit number, and the MP3 files in the folder name should start with a three-digit number.
