SparkFun Qwiic Wireless Speaker Kit

The SparkFun Qwiic Wireless Speaker Kit provides you with everything you need to make a wireless audio speaker. In order to save you as much time as possible, we've soldered male header pins on the breakout boards! Wire the circuit up, upload code to the ESP32 RedBoard IoT Development Board, configure the Qwiic-enabled Audio Codec (WM8960), connect your audio BT source, and hit play to start jamming out to your favorite tunes!

The SparkFun ESP32 IoT RedBoard that is included in this kit allows users to wirelessly stream music from an audio source to Espressif's ESP32 WROOM. The audio is then passed to a SparkFun WM8960 Audio Codec via I2S, a standard audio data protocol (not to be confused with I2C). The audio codec is a low-power, high-quality stereo codec that is chock full of features some of which include: advanced on-chip digital signal processing for automatic level control (ALC) for either the line or microphone input, programmable gain amplifier (PGA), pop and click suppression, 3D enhancement to artificially increase the separation between the left and right channels, flexible analog input pins, flexible analog signal routing, multiple boost stages, and its ability to configure I2S settings and analog audio path through software via I2C. Once the audio codec decodes the stereo signal from the DAC, the audio is sent to a desired output channel (in this case, the headphone drivers and a small hamburger mini speaker).

This kit is great for building your own wireless audio BT adapter, portable digital player, sound-reducing ear muffs, or mixing audio to an output!

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.

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.


Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Programming

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.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

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.

2 Electrical Prototyping

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.
