SparkFun Qwiic MP3 Trigger
Discontinued
The SparkFun Qwiic MP3 Trigger makes it simple to add MP3 audio playback to any project. Load MP3 files onto a microSD card, send an I2C command (or pull a trigger pin low), and your track plays through either the 3.5mm headphone jack or an external speaker connected via the poke-home connector — no soldering required.
The board features a Class-D mono amplifier capable of up to 1.4W output, 32 software-selectable volume levels, and adjustable EQ settings. When connected via USB-C, the microSD card appears as a removable drive for easy file transfer. Up to 255 tracks can be stored and triggered via I2C, while four hardware trigger pins allow instant playback of up to 10 tracks without any programming.
