OSA Electronics DACBerry ONE+ Professional Audio Soundcard

OSA DACBerry ONE+

The OSA DACBerry ONE+ is an electronic board that provides high-quality audio output for Raspberry Pi. It can be easily assembled with the Raspberry Pi using nylon screws and standoffs. The board has resistors on I2C bus and allows you to enable communication by closing the two solder jumpers. The board layout and jumper settings are provided in the user guide for easy configuration.

Assembly

Use the nylon screws and standoffs to assemble the Raspberry Pi together with the DACBerry ONE+, as shown on the image below:

Onboard Configuration
Resistors on I2C bus, allowing you to close the two solder jumpers enabling the communication.

• By default, the DACBerry ONE+ board DAC PCM5142 acts as master device, and the WM8804 as slave device, together the Pi.
• PCM5142 default I2C address is 0x4D, WM8804 address is 0x3B.
• The PCM5142 can be also configured as slave device implementing your own driver.
• The WM8804 is set by default on Hardware mode, without any I2C connection. It will get the MCLK directly from the DAC and will reproduce files at same time as the PCM5142.
• Onboard, there are several solder jumpers to configure the modes of the WM8804. You can select between Hardware/Software mode; Slave/Master mode; AIF/SPDIF Rx modes  and MCLK input selection.
• The two I2C solder jumper are by default disabled, allowing a correct communication  between the Pi and the DAC, because the WM8804 has two pull-down resistors on I2C  lines for Hardware mode. When switching to Software mode, both lines will have a pull-up resistors on I2C bus, allowing you to close the two solder jumpers enabling the  communication.

Board layout

This is the board layout:

Board Modes
The board modes disable playing simultaneously Analog and Digital using the same driver. You can switch between them applying different profiles, or you can also use both at the same time (In that case, you will need to create your own driver).
Enable Hardware Mode of WM8804 (Default):

• I2C control over WM8804 Disabled
• WM8804 in Hardware Mode
• WM8804 as Slave Device
• WM8804 MCLK from PCM5142 SCLK

This mode enables playing simoultaneously Analog and Digital using the same driver.

*Enable Software Mode of WM8804:**

• I2C control over WM8804 Enabled
• WM8804 in Sotware Mode
• WM8804 as Master Device
• WM8804 MCLK from itslef (You can use the default configuration if you plan to play Analog and Digital at same time)

This mode disables playing simoultaneously Analog and Digital using the same driver. You can switch between them aplying different profiles, or you can also use both at same time  (In that case, you will need to create your own driver).

• IMPORTANT : Modify the board at your own risk. You will need some soldering skills and tools to do it.

Jumper Settings
The DACBerry ONE+ also offers you the option to have Digital Coax IN/Out using onboard RCA connectors or using an extension board/cable. To do that, take a look at the J2 jumper configuration. By default, jumpers are located on the LEFT and RIGHT position:

Change them to the following position in order to use Digital Coax In and Out:

If you use the onboard RCA connectors for digital purpose, you can still use the 3.5mm jack for analog audio output or for optical input.
In case you want to use an external board or cable with RCA connectors in the end, this is the J2 pinout:

You will also need to take the GND from J1 connector.

SDBTM Connector

The DACBerry ONE+ is one of the first boards to include this standard created by OSA Electronics. SDB Interface is a mix of Sound and Data signals together in the same Bus. The A1 revision uses SDBTM 1.0 (like DACBerry PRO), and A2 Revision the SDBTM 1.1. This is the SDBTM connector on ONE+ board:

Quick Install

There is an easy way to install support for DACBerry ONE+ on Raspbian/Raspberry Pi OS. Just run the following code from your Raspberry Pi with Internet connectivity:

curl https://www.osaelectronics.com/get/dboneplus.sh | bash

You may need to reboot once. After rebooting, everything should work! If quick install doesn’t work at all or want to follow step-by-step instructions, please refer to the Retropie part.

Volumio Instructions

Volumio has already official support for this board, so to get it working you need to use the OSA DACBerry ONE+ profile.

• IMPORTANT : In order to make it works properly, is recommended to do a fresh install of Volumio and use lastest version.

Airplay

Volumio is a perfect choice if you want to stream music from your Apple devices.

Step 1
Open Volumio and navigate through Network in Settings Panel, and connect to your WiFi network.

Step 2
Inside Network settings, locate Hotspot Settings tab and enable it if it’s not. Restart.

Step 3
Go to your desired Apple (or Windows) device and open iTunes if you are using a computer, or open the control center if using a phone/tablet. Go to the Airplay icon and select Volumio.

Step 4
Enjoy streaming music!

Adding Password to Your Airplay Device

With the Airplay feature activated, everybody will have access to your device and will be able to play music on it. If you want to add a password to it, follow these instructions.

Step 1
Open an SSH connection to your Pi, if you can’t connect at all, enable it on volumio.local/dev. Then, type the following line to open up the template for the shairport config file in a text editor:

sudo nano /etc/shairport-sync.conf
**Step 2**

In the “general” section, add a password, like this:

Save the file as usual and reboot.

Step 3
Connect to your device, you should be prompted for a password when airplaying to it.

moOde Instructions

moOde Audio Player is one of a range of audio playback solutions that supports DACBerry boards. You can follow these instructions in order to install and configure it.  It does not offer a “ready to use” image like other distributions. Instead it uses an image of the operating system (Raspbian) as basis and then a script for automatic installation.

• IMPORTANT : In order to make it works properly, is recommended to do a fresh install of moOde and use lastest version.

Installation

Step 6
The following command executes the script. If you have not been connected to the internet two commands earlier, than simply NOTHING will happen here. If you had been online the installation wizard will be started.

sudo ./mosbuild.sh

Now a wizard will help you to do some setup:

Make the following choices:

• Write OS build directly to the boot SDCard? -> y
• Do you have a backup of your boot SDCard? -> y
• Enter Current Date (YYYY-MM-DD) -> enter date
• Make corrections -> n
• Use a proxy server for Internet access -> n
• Use a WIFI instead of Ethernet? -> n (Switching to WIFI should be done later when moOde is running.)
• Proceed with build -> y
• Power off the Pi -> y
  Wait for about 10 seconds until the green LED on Pi stops blinking. Then unplug the power cable and replug it.

All you have to do now is to wait. The Pi is downloading and compiling, so how long you have to wait is mostly depending on the CPU speed of your Pi. This may be several hours.

Configuration

Step 1
Direct your web browser to http://moode, http://moode.local or the device’s IP address.  Then, click the menu icon in the top right corner and select Configure.

Step 2
Now, select the Audio icon. Choose the HiFiBerry DAC+ board from the I2S audio device  drop-down list and click SET. 

Step 3
Restart the device and enjoy your music!

OSMC Instructions

KODI OSMC team is already working to add official support on next release, but meanwhile, you can follow these steps to make it work:

• IMPORTANT : In order to make it works properly, is recommended to do a fresh install of OSMC and use lastest version. To get it working using the RCA Output and Optical/Coax at same time, you need to use the “Hifiberry DAC Plus” profile.

Retropie Instructions
As for Raspbian Jessie, just run the following code from your Raspberry Pi with Internet  connectivity:

curl https://www.osaelectronics.com/get/dboneplus.sh | bash

The next step is to edit the raspi modules list with:

sudo nano /etc/asound.conf

This file should be blank! Just copy and paste the following text into the file:

Save the file as usual and reboot:

sudo reboot

Now to check everything is as expected, just type:

amixer

aplay -l

You should see something like that:

GPIO usage of DACBerry series boards

Many of you may would like to add some additional hardware components to your Raspberry Pi. We provide this documentation to help you with this. However:

• We do not guarantee interoperability with any other add-on card. Even if another card is not using the same GPIOs, there are many other things that might prevent interoperability. The Raspberry Pi GPIOs are not designed as a bus system (even the I2C bus can’t be simply used by multiple cards as there might or might not be the right pull-up resistors on every I2C slave).
• Soldering on the DACBerry boards voids warranty. There is no replacement for boards that have been modified.
• There is no support from us. You can ask questions in our forums. There are already interesting projects and other users might help you.
• Do not use more than a few mA from the 3.3V line. If your circuit requires 3.3V, use the 5V power rail of the Raspberry Pi with an additional voltage regulator.
• Pin 27 and 28 are always reserved for an ID EEPROM on the Raspberry Pi. Independently which card you use, these pins are always reserved and should never be used to connect external components.
