DA7212 I2S Audio Board For Raspberry Pi, Stereo Encoding/Decoding, Onboard Dual Microphones

DA7212 I2S Audio Board
for Raspberry Pi

Supports stereo encoding/decoding and rich audio processing functions

Designed for the Raspberry Pi 40-pin GPIO header, this module is fully compatible with Raspberry Pi series boards. It features the high-quality DA7212 stereo DAC, controlled via I2C, with audio data transmitted over the I2S interface for reliable performance.

A standard 3.5mm headphone jack is included for convenient audio output, along with an onboard AUX input for connecting external audio sources. For speaker integration, the board provides both a screw terminal and dual-channel PH2.0 speaker headers, making it suitable for a wide range of applications.

Dual onboard microphones enable audio recording without the need for additional hardware, while a programmable button and status indicators allow for custom functionality and user interaction.

The module supports audio sampling rates up to 96kHz and delivers high-resolution sound with up to 24-bit audio data support.
