SparkFun Qwiic Wireless Speaker Kit

Everything you need to build a wireless Bluetooth audio speaker. The kit centres on the ESP32 IoT RedBoard for Bluetooth streaming and the WM8960 Audio Codec for high-quality stereo decoding via I2S. Connect your phone or tablet via Bluetooth, hit play, and listen through the included mini speaker or headphones via the 3.5 mm TRRS breakout.

The WM8960 codec features automatic level control, programmable gain, pop/click suppression, 3D stereo enhancement, and configurable I2S settings via I2C. All boards come with headers pre-soldered for quick breadboard assembly.
