1. General
The Innomaker HiFi DAC Hat is the best optimized partner for RPI audio output. Used on-board
PCM5122 as the IIS clock master , instead of the clocks from RPI which comes with too much
jitter. Added dual low jitter oscillators(45.158M and 49.152M) to support more exact sample rate
clocks. No soldering, no additional cables. Just plug it in and do some simple configuration, You
can get a same high-class music player, but only pay 1/10 to 1/100 of the market price.
2. Features
1. Compatible with Raspberry Pi Zero,Zero W,3B,3B+with the 40-pin connector. Connects directly
to the Raspberry Pi board, no additional cables required,no soldering. Easy to get more beautiful
and fantastic sound by this RPI+DAC HIFI suits.
2. Absolutely perfect to support all Raspberry Pi music playback system ,such as OSMC, Max2Play,
RuneAudio, Volumio, Moode, PiCorePlayer, PiMusicBox, OpenELEC, Debian, Ubuntu etc. Support
play music from a hard disk or over the network. Support DSD over PCM(DOP)mode.
3. Class-leading stereo audio DAC PCM5122, sample rates up to 384-KHz/32-Bit. Paired with
stereo high fidelity headphone amplifier TPA6133. Provides 2.1Vrms ground-centered outputs
coupled with Film capacitor.
4. On-board a pair of gold plated RCA (LEFT &Right) jacks and a 3.5mm high-end headphone jack
output, allow you free to play your music through Raspberry Pi to another terminals.
5. Comes with software, document and friendly technology support. For more information
please refer to our wiki（view the link on color page comes with the goods).
6. On-board EEPROM and Infrared receiver extended function(Default no soldering)

IR is connected to PIN37(GPIO_26) , But we have no software for it right now. We will release
new software version after finish it. If you have any advices please feel free to E-mail to us.
2) ID EEPROM: (U5, No soldering on-board )
Pin 27 and 28 are always reserved for an ID EEPROM on the Raspberry Pi. Independently
which card you use. It’s useless for most application. If you want to use this function, you
need to solder the IC, resistance and capacitance by yourself.
3) USER EEPROM: (U8 No soldering on-board )
It connected to the same IIC port with DAC. you need to solder the IC and Confirm IIC slave
devices. If you a novice of Raspberry Pi, We really wouldn't advise do that.

4. Software Description
4.1 Overview
HIFI DAC HAT module compatible with many Raspberry pi music playback system such as:
OSMC / Max2Play / RuneAudio / Volumio / Moode / PiCorePlayer / PiMusicBox / OpenELEC etc.
You can choose your favorite. We take Volumio/MoOde/Max2play/Debian Preset System for
Example.
Note:
1) Because the third party will update the version unscheduled, so the actual UI may different
from below user guide. But the configurations will be the same. If you meet any problem, you can
2) Check the user help on the website of the third party or feel free to e-mail us.
3) The default sound is loud of most system, it’will offensive your ears. So please turn down the
volume before you enjoy it.
4) For some music systems that are not listed, you can try to set as below step. Many thanks to
the friendly customer named ‘HoweTechnical’write it down on our Amazon review page.
a. SSH into your RPI (won't go into how to do that, Google it if you need)
b. Type "cd .." and press enter (no quotes)

4.4 VOLUMIO Setup
Volumio is an entirely new music system. It is designed to play all your music, whether is an
Hi-Res file or a Web Radio, with the highest quality. Control it with your favourite device, a
smartphone, PC or tablet, and enjoy your music as you never did before.
Volumio is a Free and Open Source Linux Distribution, designed and fine-tuned exclusively for
music playback. I supports all filetypes: FLAC, Alac, Aac, Vorbis, Mp3, DSD etc. and support
By flashing (installing) Volumio on any platforms, it will then become a headless Audiophile Music
Player. Headless means that the only way to control it will be with another device, such as a
Smartphone, Tablet, PC or anything that has a browser.
For more detail please refer to https://volumio.org/discover/.
STEP:
1) Insert the TF card with volumio image into the Raspberry pi then power on.

2) By using your smart phone, tablet or any device with WIFI and browser search for WIFI
hotpots. You can see a ‘Volumio’ name in the search list. Connect this hotspot with password
‘volumio2’. You can change your password after login.
3)The browser will automatically eject playback software UI which is based on web interface ( if
you connect the hotspot successfully but for some reason browser can’t pop up the playback
page automatically, you can using http://192.168.211.1 to login. You can see below wizard of
Volumio. We only need to set “Language”,“Name” “Output”and “Done”for simple application.
