The Qwiic Tsunami Super WAV Trigger is a powerful audio module based on the ARM Cortex M7. It can simultaneously play up to 25 mono or 13 stereo uncompressed 44.1kHz, 16-bit tracks. Each track can be independently controlled, allowing users to create a mix of music, dialog, and sound effects. It also supports seamless looping over any track length. The module uses the Qwiic system, making it easy to connect without soldering, but also includes 2.54mm-spaced pins for those who prefer direct access to each pin.
The Qwiic Tsunami Super WAV Trigger boasts eight audio output channels, which can be arranged as eight mono or four stereo pairs. Users can choose between mono or stereo firmware versions. The mono version includes a new “Synced Set” trigger function that can start up to eight mono tracks on adjacent outputs, perfect 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). Arduino and Python libraries are readily available for the Tsunami.
This module comes with a dedicated MIDI port with an integrated opto-isolator, simplifying the connection to any MIDI controller. The 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. The module operates on 3.3V, and its inputs, including triggers and serial RX, are not 5V tolerant.
It is crucial to ensure that your microSD card is formatted with the correct file allocation size (32Kb) for the Qwiic Tsunami Super WAV Trigger to function properly. Incorrect formatting may result in erratic behavior and occasional crashes.
The SparkFun Qwiic Connect System is a comprehensive ecosystem of I2C sensors, actuators, shields, and cables designed to make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, reducing the required PCB space and preventing incorrect hook-ups due to polarized connections.
The Qwiic Tsunami Super WAV Trigger supports up to 4096 uncompressed 16-bit, 44.1kHz mono or stereo WAV files, provides real-time playback rate control, and offers seamless looping over arbitrary track lengths. It features 16 trigger inputs that can be individually selected for contact closure or 3.3V control. The trigger inputs can also be individually inverted and set to be edge, latched or level sensitive. The module also offers adjustable output volumes, firmware track fades, and a dedicated “Play” status digital output pin. It also provides extensive serial control and is pin compatible with SparkFun FTDI Basic 3.3V. Power can be supplied through USB-C and PTH inputs.
