Our Raspberry Pi HiFi sound card, HiFi DAC v1.0, launched at the end of 2016, has been recognized by Raspberry Pi enthusiasts and music lovers for its excellent usability and cost-effectiveness over the past year. Recently, we have made improvements to this product based on updates to Raspberry Pi software and hardware, as well as user feedback. Today, we are launching the HiFi DAC v1.1.
The main adjustments this time include:
-
Adoption of a modular GPIO pin socket design, allowing for the selection of long or short pins for easy assembly and disassembly. Users can utilize long pin sockets to access the GPIO pins of the Raspberry Pi and stack other expansion boards or use Dupont wires for extended functionality.
-
Distinction between the standard version and the version with RCA sockets. The standard version is equipped with a 3.5mm headphone socket and reserved RCA solder points, saving space, and can directly stack other compatible Raspberry Pi expansion boards with the long pin socket; the version with RCA sockets includes both a 3.5mm headphone socket and RCA terminals, suitable for scenarios requiring both headphones and speakers.
-
It is recommended to use a mobile phone instead of a remote control, with the infrared receiver not soldered by default (but corresponding solder points are reserved).
-
PCB beautification, making it more streamlined and refined.
This product is aimed at music lovers and integrates the professional audio decoding chip PCM5122 from TI, utilizing the I2S interface standard to create a complete audio hardware decoding system based on Raspberry Pi.
It supports powerful playback software such as Volumio, RuneAudio, OSMC, making it the best choice for quickly building a Raspberry Pi HiFi system!
HiFi DAC is compatible with Raspberry Pi 1 A+, B+, Raspberry Pi 2 B, Raspberry Pi 3 B, B+, Raspberry Pi Zero, Zero W, and subsequent Raspberry Pi series hardware that are compatible with this standard.
Features
-
Utilizes the professional audio decoding chip PCM5122 from TI, supporting sampling rates up to 32bit/384kHz, dynamic range of 112dB, and distortion of -93dB. It features a low-noise voltage regulator design and uses magnetic beads for grounding to eliminate current noise.
-
3.5mm headphone socket and reserved RCA solder points, suitable for various scenarios including speaker amplifiers and headphone amplifiers. Just plug the expansion board directly onto the Raspberry Pi to use it, utilizing the I2S interface for direct digital-to-analog decoding, rather than a USB DAC method.
-
DAC decoding status indicator light, which lights up during decoding and goes out when stopped or not in use, providing better insight into the DAC’s operating status.
-
Modular GPIO pin socket design, allowing for the selection of long or short pins for easy assembly and disassembly. Users can utilize long pin sockets to access the GPIO pins of the Raspberry Pi and stack other expansion boards or use Dupont wires for extended functionality.
-
Original imported components to ensure the performance and lifespan of each product.
-
Perfectly compatible with the official Raspberry Pi HAT dimensions, the circuit board uses high-quality gold immersion technology, and the optimized wiring design ensures better signal impedance continuity, reducing signal reflection and refraction.
-
Reserved infrared receiver function design, allowing for the addition of infrared remote control support to control volume, playback operations, etc.
Modular long and short pin socket design, allowing for the selection of long or short pins for easy assembly and disassembly. Users can utilize long pin sockets to access the GPIO pins of the Raspberry Pi and stack other expansion boards or use Dupont wires for extended functionality. Installation effects are shown in the image.
Software Features
-
Supports powerful playback software such as Volumio, RuneAudio, OSMC, enabling playback of audio formats including FLAC, WAV, MP3, AAC, ALAC, PLS, and supports lossless formats.
-
Direct reading of audio playback from music libraries via Samba, NFS, local area network sharing, USB drives, and external hard drives.
-
Streaming of online audio radio.
-
Support for Airplay audio playback.
-
Support for DLNA indexing.
-
Web UI player, allowing connection to the player and control of playback via PC, tablet, mobile phone, or APP.
-
Powerful configuration page to set up wireless network connections, playlists, and other configurations.
