Raspberry Pi Audio DAC SHIM (Line-Out)

Beschrijving Raspberry Pi Audio DAC SHIM (Line-Out)

• PCM5100A DAC-chip (datasheet)
• Digitale audio op lijnniveau (24-bit / 192 KHz) via I2S
• 3,5 mm stereo-aansluiting
• SHIM-formaat bord met frictie-fit connectoren
• 2x bevestigingsgaten (M2.5) voor als je alles aan elkaar wilt bevestigen met bouten
• Volledig samengesteld
• Solderen is niet nodig (*tenzij je een Pi gebruikt die zonder header wordt geleverd)
• Compatibel met alle 40-pins header Raspberry Pi-modellen
• Afmetingen: 66,5 x 16,2 x 5,2 mm (L x B x D, inclusief 3,5 mm-aansluiting)

Software Audio DAC SHIM (Line-Out)

The easiest way to get everything set up is to to use our Pirate Audio software and installer which configures I2S audio and SPI, as well as installing Mopidy and our custom Pirate Audio plugins which will let you stream Spotify or play local files.

Here's how to get started:

1. Set an SD card up with the latest version of Raspberry Pi OS.
2. Connect to Wi-Fi or a wired network.
3. Open a terminal and type the following:git clone https://github.com/pimoroni/pirate-audio
cd pirate-audio/mopidy
sudo ./install.sh
4. Reboot your Pi

You can find more detailed instructions here: https://github.com/pimoroni/pirate-audio/tree/master/mopidy or get tons more info in our Getting Started with Pirate Audio tutorial.

Alternatively, if you'd rather not install all the Mopidy stuff, you can set Audio Amp SHIM as your default Alsa device in Raspberry Pi OS by adding the following lines to your /boot/config.txt file:

dtoverlay=hifiberry-dac
gpio=25=op,dh

If you're using a Pi that has an audio jack you might also need to disable onboard audio by adding a # to the beginning of the following line (this can help applications find the correct audio device automatically):

#dtparam=audio=on

Notes

• You can use an Audio DAC SHIM with HATs and mini HATs without a booster header, as long as they don't have any chunky components on the underside (it's a good idea to check there are no metal components on the underside of your HAT that touch the metal components on the top of the SHIM).
• If you want to use one with a Pibow Coupé case (either for the Zero / Zero W or Pi 4), then you'll need to use a booster header to raise it up a little.
• If you're planning on using Audio DAC SHIM to add an audio output to your Pi 400, you'll also need a booster header. If you're plugging it directly into the back of a Pi 400, bear in mind that the SHIM should be upside down, with the mounting holes at the bottom. Alternatively, you could plug it in via a Flat HAT Hacker (in which case you won't need a booster header or to plug anything in upside down).
• Audio DAC SHIM uses GPIO 18, 19, and 21 (as well as 5v and various Grounds). If you're planning on using it in conjunction with other boards you'll need to check for pin conflicts using pinout.xyz.
