ES9023 I2S HIFI DAC Board for Raspberry Pi

This I2S DAC expansion board is designed to plug directly into the Raspberry Pi GPIO header, providing a high-fidelity audio solution without complex wiring. Based on the ESS ES9023 DAC chip, it supports audio formats up to 192 kHz / 24-bit and reduces CPU load by utilizing the I2S interface.

The board features analog outputs via a 3.5 mm headphone jack and an RCA socket, powered directly from the Raspberry Pi's GPIO pins. It also includes an onboard infrared receiver (38 kHz) for remote control functionality and a 3.96 mm connector for optional 5V DC power input.
