With 6x flexible analog input pins, the SparkFun WM8960 Audio Codec Breakout can accommodate a variety of sound source signal types, from line level to microphone level (balanced and unbalanced) sources. This makes it possible to accept audio from computer sound cards, smartphone headphone outputs, electret microphones, MEMs microphones and more. The flexible analog signal routing includes PGAs and multiple boost stages to accept a wide range of audio signal levels.
The efficient class-D driver ensures low heat and long battery life when driving 8Ω speakers at up to 1W per channel for portable audio applications. Alternatively, it can drive 16Ω headphones at up to 40mW. The 3D enhancement feature can be used to increase the separation between the left and right channels, creating a fuller, more immersive sound experience.
The SparkFun WM8960 Audio Codec Breakout is easy to connect to a breadboard, with the WM8960 pins broken out along the edge of the PCB with 2.54mm-spaced pins. The Qwiic system allows for simple wiring of the I2C port when configuring the audio codec's settings. A power LED (PWR) is included on the board to indicate when power is applied. The board also includes a built-in XC6222 3.3V/700mA voltage regulator to regulate the voltage for the analog circuit, along with jumpers for users who want to power each with a separate power supply.
The SparkFun WM8960 Audio Codec Breakout is an excellent choice for projects requiring the encoding or decoding of audio signals. It's perfect for use in portable digital players or immersive VR games. The board is part of the SparkFun Qwiic Connect System, an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error.
The board weighs 4.1g and measures 25.4mm x 40.6mm.
