1. Product Overview
This board supports audio playback and recording, stereo codec, onboard headphone output and microphones, and includes an onboard 0.96-inch OLED display.
The WM8960 Stereo Audio Codec Expansion Board is designed for the Raspberry Pi series and is an ideal solution for embedded audio applications. Based on the high-performance WM8960 chip, it supports both audio output (playback) and audio input (recording). It can directly drive speakers for music playback with clear, transparent stereo sound, meeting diverse needs such as music playback and audio acquisition. The board integrates a highly compatible headphone jack and microphones, enabling plug-and-play audio usage without additional external devices. With the 0.96-inch OLED, the working status can be displayed visually for intuitive operation. The onboard 40-pin female header is fully compatible with Raspberry Pi boards, allowing easy audio expansion without complicated wiring. It is suitable for maker projects, smart hardware prototyping, teaching experiments, and audio device modifications, providing a stable and reliable audio solution.
2. Product Features
· High-Performance Codec Core: Powered by the professional WM8960 audio chip, supporting stereo encode/decode with excellent sampling and audio quality. Supports stereo effects such as 3D surround, and meets bidirectional requirements for both playback and recording across multiple audio processing scenarios.

Notes
· To use the audio functions of the expansion board, you need to disable/mask the Raspberry Pi's default audio.
· The board supports recording and playback simultaneously. After running the program, you will hear the microphone-captured sound through headphones or speakers. Do not place/operate the speaker too close to the microphone, otherwise acoustic feedback may occur and cause howling/squealing.
