Sometimes you just need an MP3 to play. Whether it's a theme song as you enter the room or a power song when you are working out. The SparkFun Qwiic MP3 Trigger takes care of all the necessary requirements, all you need to do is send a simple I2C command and listen to whatever is on your micro SD card. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.
When a USB-C cable is connected to the Qwiic MP3 Trigger the contents of the microSD card appears as a jump drive. Simply plug in the Qwiic MP3 Trigger and you'll be transferring MP3s, no need for drivers and no need for WAV or Vorbis conversion! Sound output is provided via a 3.5mm headphone jack or poke-home connector allowing an external speaker to be connected without soldering. Your supplied speaker is boosted by a Class-D mono amplifier capable of outputting up to 1.4W making it capable of being incredibly loud! Volume is software selectable between 32 levels while equalization can be tuned to be sure your classical hits sound different from your jazz dance routines. If you don't want to deal with any programming, there are four trigger pins. When pin 3 is pulled low the T003.mp3 file will immediately be played. This allows you to start playing sound effects with the touch of a button! By pulling multiple pins down simultaneously the four triggers can play up to ten tracks: T001 to T010. Up to 255 tracks can be loaded onto the SD card and triggered via the I2C interface.
All settings including volume, EQ, and I2C address are stored in NVM and loaded at each power up. The I2C address of the Qwiic MP3 Trigger can be modified via a solder jumper or be assigned using a software command. Multiple Qwiic MP3 Triggers can be chained together on a single bus allowing for simultaneous track mixing and triggering.
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.
This revision of the SparkFun Qwiic MP3 Trigger, we have only made one change to improve the ease of use of the board, listed below. If users are unsure about which version they purchased, please refer to the product pictures.

These boards are supposed to be nearly plug-and-play, however they don't enumerate as USB drives under any of my computers, windows or linux. Sparkfun sent me both a replacement board and sd-card. Neither one will enumerate. I managed to load files onto the card externally, and on the replacement board they play in an endless loop when triggered.
I don't know if someone substituted chips, or they are just faulty, but they don't work.
And my last emails to sparkfun asking them to test a few off out of their stock have gone unanswered. Complete 100% fail. I'll be getting my boards off ebay for now on.
The connection to the host isn't stable, so it is better to transfer files some other way. Everything else works perfectly and VERY fast (I had to sync it to my light show project)
I ordered one of these modules and they do no work properly. The module does not stop/pause the current playing file. And on top of that, the module plays the same music file over and over in an endless loop. Sparkfun, my email I sent you a week ago has not been answered. Which means you are already aware this product does not work properly. Sparkfun please answer and handle customer technical issues in a timely manner. Taking 3 days to a week is too long for not answering or handling customer technical issues.
