Qwiic MP3 Trigger - MP3 player module

Description

MP3 player module controlled by the I2C interface. It is based on a class D amplifier with a power of 1.4 W. The board has a 3.5 mm headphone output and an 8 Ω speaker connector. Audio files are saved on the microSD card via the USB interface (USB Type-C connector). The protocol allows you to play one of 255 files stored on the card. It is also possible to run the player without I2C communication - just use one of the 4 trigger pin configurations and the selected file will be played (allows you to play files from T001 to T010). The playback parameters are saved on non-volatile memory, thanks to which the last settings will be loaded the next time the device is started. The product page includes the user manual and the Arduino library.
