The kit contains a MP3 player module that is based on a high-quality MP3 audio chip. It can support 8k Hz ~ 48k Hz sampling frequency MP3 and WAV file formats. There is a TF card socket on board, so you can plug the micro SD card that stores audio files. MCU can control the MP3 playback state by sending commands to the module via UART port, such as switch songs, change the volume and play mode and so on.It can directly connect to headphone and the power amplifier speaker. Onboard XH2.54-2P nest, it can connect to a small 8 ohm / 1W speaker.
