Introduction

The ESP module can control the MP3-player module "DRPlayer Mini (DFR0299/YX5200)" and the "YX5300" module with 3.5mm output for speaker(s). Other than MP3 (sampling frequencies up to 48kHz) WAV files are also supported. The file names can be whatever but if you would like to be sure to play the correct file you should use the following name schema:

0001.mp3, 0002.mp3, 0003.mp3 ... 2999.mp3, 3000.mp3
