High-Fidelity Audio Expansion for ODROID
ransform your ODROID SBC into an audiophile music streamer with 24-bit/192kHz resolution and optical output.
Transform your single-board computer into an audiophile-grade music streamer with the ODROID HiFi Shield 2. Powered by Texas Instruments' high-end Burr-Brown PCM5242 DAC chipset, this expansion board delivers high-resolution audio decoding up to 24-bit/192kHz with minimal distortion. It features an onboard ultra-low-noise dropout (LDO) regulator to isolate power ripple, resulting in an outstanding signal-to-noise ratio and clean, dynamic sound—making it a perfect choice for dedicated hi-fi setups.
Designed for flexible output, the HiFi Shield 2 includes gold-plated stereo RCA connectors as well as an S/PDIF Optical (Toslink) output for digital passthrough. It mounts directly via the dedicated 7-pin I2S expansion header, preserving valuable USB ports while ensuring low-jitter master-clock synchronization. With hardware-level volume and mixer controls accessible via the I2C bus, it integrates seamlessly into headless Linux audio distributions like Volumio, DietPi, and Kodi/XBMC.
