Acogedor HiFi Converter Sound ES9023 Dual Decode I2S 192kHz DAC Expansion Rugged PCB and Analog Output Digital-to-Analog Card, Chip, Bus, 24-bit Box,

Dual Decoding Architecture: Designed with a dual decoding chip, this board processes left and right channel sound signals simultaneously, reducing channel crosstalk while improving sound separation and dynamic range, resulting in a clearer, more layered listening experience that meets HiFi-grade sound requirements. I2S Bus Transfer: Data is transmitted via the I2S digital sound bus, significantly reducing digital signal interference compared to standard SPI or USB transfers. It preserves sound detail and is particularly suitable for lossless transfer of high sample rate sound files, meeting the stringent signal integrity requirements of HiFi sound. Compatibility: The HiFi sound card expansion board is designed to fit Pi 4B, 3B+, 3B, 3A, 2B, ZER0(W), and 2W, and features a robust PCB construction for reliable performance. Professional Sound Interface: Equipped with analog sound output jacks that can be directly connected to conventional sound equipment. Furthermore, it features separate power supplies for digital and analog, reducing interference to the audio signal from power supply noise, ensuring stable output quality, and adapting to a wide range of HiFi peripherals and usage scenarios. Powerful Expandability: Specifically designed to fit the RasPi 4B, this board connects directly via expansion headers without the need for additional adapters. Quickly transform your RasPi 4B into a high-performance sound decoding hub, allowing you to build a simple HiFi playback system by connecting a sound amplifier and speakers, and it works with a variety of sound software and systems.
