We’ve written an extensive Arduino library to make MP3 playing over I2C a breeze. Play tracks,

change volume, play next/previous, check if track is playing, stop play, change EQ, and change I2C

address are all supported.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables

that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm

pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized

connections mean you can’t hook it up wrong.



FEATURES



Operating voltage: 3.3V



Current consumption:

40mA standy

40mA when playing over headphones at any volume level

150mA-300mA when driving external 8Ω speaker at full volume setting



microSD supports 128MB to 32GB cards



Volume, EQ setting, and I2C address settings stored in non-volatile memory and loaded at

each power-on



WT2003S MP3 decoder IC provides USB access to microSD socket (up to 32GB) and MP3

decoding



ATtiny84 receives I2C commands and controls the MP3 decoder



Poke-home connector allows for sturdy but temporary speaker connection without soldering



Trigger pins 1, 2, 3, and 4. When pins 1+4 are pulled low simultaneously T005.mp3 will play



Built-in TPA2005D1 based 1.4W Class-D mono amplifier



Address jumper to select between I2C address 0x37 (default) and 0x38. I2C address is also

configurable via software to one of 110 different addresses.



USB-C Connector



Qwiic Connector
