Compatibility: HiFi sound card expansion board is designed to fit for Pi 4B 3B+ 3B 3A 2B ZER0(W) 2W, featuring a sturdy PCB construction for reliable performance.
Dual Decoding Architecture: Designed with dual decoding chips, this board processes left and right channel sound signals simultaneously, reducing channel crosstalk while improving sound separation and dynamic range for a clearer, more layered listening experience that meets HiFi grade sound requirements.
I2S Bus Transfer: Data is transmitted via the I2S digital sound bus, which significantly reduces digital signal interference compared to standard SPI or USB transfer. It preserves sound details and is especially suitable for lossless transfer of high sample rate sound files, meeting the strict signal integrity demands of HiFi sound.
Strong Expandability: Specifically designed to fit for RasPi 4B, this board connects directly through the expansion header without any additional adapter. It quickly turns your fit for RasPi 4B into a high performance sound decoding hub, allowing you to build a simple HiFi playback system by connecting an sound amplifier and speakers, and it works with various sound software and systems.
Professional Sound Interfaces: Equipped with analog sound output jacks for direct connection to traditional sound equipment. It also features separate digital and analog power supply designs to reduce power supply noise interference with the sound signal, ensuring stable output quality and adapting to a wide range of HiFi peripherals and usage scenarios.
