## Overview

The DollaTek HIFI DiGi+ Digital Sound Card is a high-fidelity audio upgrade for Raspberry Pi models A+, B+, 2B, and 3B. Featuring a dedicated WM8804G chip, dual low-jitter oscillators, and full galvanic isolation, it delivers bit-perfect 192kHz/24bit digital audio via optical and coaxial outputs. Its plug-and-play HAT design requires no soldering and draws power directly from the Pi, making it the perfect choice for audiophiles seeking premium sound quality and seamless integration.

## Description

Features:1. Dedicated WM8804G digital chip and S/PDIF interface chip supports up to 192kHz/24bit resolution2. Dual low-jitter oscillators used for clock generation3. Two separate oscillators for 44.1 and 48kHz provide the optimal clock frequencies for all sample rates.4. Full galvanic isolation between the Raspberry Pi and your DAC on the electrical output5. Bit-perfect output, audio data stream will not be modified in any way6. Gold plating PCB board, arc wire PCB design reduce the signal reflection and refraction.7. The output port use optical and coaxial two output interface, convenient for the user to connect an external amplifier8. Integrated infrared receiving function, more convenient to control the playback when network is unavailable9. The board conforms for Raspberry Pi hardware-attached-on-top (HAT) specification. Connects directly to Raspberry Pi just plug in, no soldering required.10. Compatible with Raspberry Pi Model A+\ B+\ 2B\ 3B and Zero.11. Directly powered from the Raspberry Pi, no additional power supply necessary12. Support access to all GPIO.Package Included:1 x DIGI Pro Sound card

Review: The card performs as expected - The card works perfectly, mechanically and electrically, on a Raspberry Pi 3A+ running piCorePlayer / Squeezelite. I have not tried out the card's IR receiver. Squeezelite audio output settings I have successfully used are "HiFiBerry Digi+ Pro" and "HiFiBerry Digi2 Pro". These HiFiBerry "Pro" boards seem to use the same interface chip and have dual crystal oscillators as in this DollaTek product so this is as expected.
Review: Great value - Hi-fi Berry Digi + for half the price - Slapped it onto an RPi 3 streamer build based on MoOde, it's detected as a Hi-fi Berry Digi + and works just fine. I've found that the optical sounds better than the coaxial where usually it's the opposite, great value!

### ⭐⭐⭐⭐⭐ Great Sound Great Price
*by L***N on 9 April 2020*

This was an experiment really. I wanted to add a RPI based streamer to my hifi system to run Volumio. Some of the I2S to Spdif hat boards available cost a fortune and I didn’t want to commit to significant expense until I had proved that this was how to do what I wanted. I saw this while looking for a low cost hat board and noticed not only the chip quality but also the onboard power filter. For the price this is brilliant. I have a good system and this way out plays it’s cost. Streaming flac files over my home network from a headless Ubuntu server means that I hardly need another audio source. If you have a PI and an external DAC you can’t go wrong.
