The MP3 Player kit is designed specially for voice broadcast projects, such as bus stop announcement system, clock broadcast system, door welcoming system, ATM machines tone systems, and MP3 / wave file playback voice project.
The kit contains a high quality OPEN-SMART UNO board which is improved Arduino compatible development board based on ATMEGA328P. Black board and the colorful female pin headers make your project more impressive and unique. It is very popular Arduino project production.
The kit contains a MP3 player module that is based on a high-quality MP3 audio chip. It can support 8KHz~ 48KHz 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 8ohm / 1W speaker.
