Based on a new generation ARM Cortex M7, this version of the Qwiic Tsunami Super WAV Trigger extends polyphony to 25 mono or 13 stereo simultaneous uncompressed 44.1kHz, 16-bit tracks. Each track can start, pause, resume, loop, and stop independently, and can have its own volume setting, allowing you to create the perfect interactive mix of music, dialog, and sound effects. The Qwiic Tsunami also supports true seamless looping over an arbitrary track length. 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 have full access to each pin.
The big news is that the Tsunami has eight audio output channels, arranged as either eight mono or four stereo pairs. Alternate versions of firmware support either mono or stereo architecture – you choose. The mono version adds a new “Synced Set” trigger function that can start up to eight mono tracks on adjacent outputs. These tracks will start and stay in sample-sync for playing stereo or even 5.1 or 7.1 surround sound content with a single trigger. Any track can be dynamically routed to any output. And each output provides independent real-time volume and sample-rate conversion (pitch bend). For your convenience, the Tsunami also has full Arduino and Python libraries available which can be found in the Documents tab above!
Each Tsunami Super WAV Trigger has a dedicated MIDI port with an integrated opto-isolator, making it easy to connect to any MIDI controller. Tsunami’s MIDI implementation includes control of volume, pitch bend, attack and release times, and the ability to route any MIDI key to any of the output channels, as well as specifying single-shot or looping playback per key. It is very important to know that this is a 3.3V device, and its inputs – including triggers and serial RX – are not 5V tolerant!
Note: The Tsunami Super WAV Trigger will only work properly if your µSD card is formatted with the correct file allocation size (32Kb). If this is set incorrectly during formatting, then the Tsunami will show very erratic behavior and occasionally crash.
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.
1 Note: The original Tsunami Super WAV Trigger (Qwiic) supports 32 mono or 18 stereo tracks independently and simultaneously, but is facing supply chain constraints. If 25/13 voices is enough for your project, you have come to the right board!
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Does this mean the total size of all the .wav files has to be under 32Kb? If so, that's not a lot of audio.
No. Not sure what gave you that impression. Total WAV file size is limited only by the size of the FAT16 or FAT32 microSD card - up to 32GB.
The schematic (pdf) under documents is missing the second sheet.
Oops. Sorry about that. I exported it again with both pages and reuploaded it. Try again.=)
