Qwiic MP3 Trigger

The Qwiic MP3 Trigger is designed to operate at 3.3V and must not be powered above 3.6V as this is the maximum operating voltage of microSD cards. Otherwise, the board can also be powered through the Qwiic connector.

MP3 and ATtiny84

At the heart of the Qwiic MP3 Trigger is the WT2003S MP3 decoder IC. This IC reads MP3s from the microSD card and will automatically mount the SD card as a jump drive if USB is detected. The ATtiny84A receives I2C commands and controls the MP3 decoder.

Audio Amplifier

The speaker is boosted by a Class-D mono amplifier capable of outputting up to 1.4W. Both outputs have volume controlled by the SET_VOLUME command and is selectable between 32 levels.

Audio Outputs

This is a friction fit type connector; simply push stranded core wire into the hole and the connector will grip the wire, speaker as Dayton audio reference 3″ full-range drive.
