DollaTek HIFI DiGi+ Digital Sound Card I2S SPDIF Optical Fiber RCA for Raspberry Pi 3 2 model B B+

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.

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!

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.

pitch is a mile out male voices sounded female, might be just a bad board. Think some one else had the same problem

Tried on two different Raspberry Pi's and both have the same problem. Possibly a faulty board. I have no ordered the real thing from Hifi Berry.

This arrived today, I was having problems with the audio through the USB port so I thought I would try one of these. Connected to my Pi4 then ran Picoreplayer changed the setting in the sound card settings and I was done. Very simple to setup and so far sounding great and plays upto 192khz files. At £18.99 it's a bargain

The board fits easily in the rpi3 with the standoffs giving a good grip to the optical and coaxial ports. I installed piCore on the sd card as a player Squeezelite for my network.

It simply works. No issues with picore player or any other players.

Acheté pour pouvoir bénéficier du son original sur un ampli surround qui ne disposait pas de port HDMI. Très efficace et mieux qu'un boîtier externe qui sépare les signaux.

Habe es für ein Webradio verwendet das per TOSLINK ein digitales Signal an den Hifi Verstärker sendet. Klappt einwandfrei. Man muss sich nur im klaren darüber sein daß dies keine Soundkarte in dem Sinne ist daß sie Klang erzeugt oder einen DAC besitzt. Es ist einfach ein Adapter vom Raspberry I2S Bus auf PCM über Coax oder Optisch.

Raspberry Pi 4 Modello B (4GB) preso giugno 2020 su amazon funziona perfettamente, sostituito al Bewinner I2S Interfaccia Hifi Digi Dac + Hifi Digi che non era male ma volevo sfruttare il Topping E50 su uscita coax e funziona perfettamente, provato anche ad entrare nel Cambridge audio CXA81 (per provare il suo DAC interno) tutto perfetto, Volumio lo ha riconosciuto subito una volta impostato come dac, non ho dovuto neanche reinstallarlo,swap e via piattaforma test: Rasperry con Dolla Tek+Topping E50+AA Puccini Anniversary+ProAc DT8 Software streaming Volumio SSD 1tb collegato al Raspy vale la spesa sicuramente

Using it with Volumio as a "HiFiBerry Digi+ Pro" which works great. Arrived with the IR receiver squished down and shorting out which caused the whole board to not function at all. After bending the IR receiver back up everything started working (except possibly the IR receiver which I have not tried to use). Has a very bright green LED which can be annoying.

Clonada de la Hifiberry Digi. Funciona perfectamente tanto con la conexión óptica como la coaxial.
