Output punchy digital I2S audio whilst leaving your GPIO pins conveniently accessible.\u003c\/p\u003e\n\u003cp\u003eSHIM is a old Yorkshire term meaning 'Shove Hardware In Middle' - we use it for our Raspberry Pi add-ons that are designed to be sandwiched between your Pi and a HAT or mini HAT. This one has a \u003cstrong\u003eclever friction fit header\u003c\/strong\u003e which slips handily over your GPIO pins and is \u003cstrong\u003eeasily removable \u003c\/strong\u003e- great for prototyping.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ePCM5100A DAC chip\u003c\/strong\u003e takes high quality digital audio from your Pi and pipes out crisp, line-level 24-bit \/ 192KHz stereo audio through the 3.5mm jack. Because Audio DAC SHIM adds no extra bulk to your Pi it's perfect for fitting inside sleek cases or hiding inside hi-fis, media centres or radiograms - letting you play music or stream digital radio through that still perfectly good sound system. It's also a handy way to add an an audio output to your Pi Zero or Pi 400!\u003c\/p\u003e\n\u003cp\u003ePlease note \u003cstrong\u003ea Raspberry Pi is not included\u003c\/strong\u003e with this board (but check out the extras tab if you'd like to buy one!)\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePCM5100A DAC chip (\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/pcm5100a.pdf?26823\" target=\"_blank\"\u003edatasheet\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003eLine-level digital audio (24-bit \/ 192KHz) over I2S\u003c\/li\u003e\n\u003cli\u003e3.5mm stereo jack\u003c\/li\u003e\n\u003cli\u003eSHIM-format board with friction-fit connectors\u003c\/li\u003e\n\u003cli\u003e2x mounting holes (M2.5) for if you want to secure everything together with bolts\u003c\/li\u003e\n\u003cli\u003eFully-assembled\u003c\/li\u003e\n\u003cli\u003eNo soldering required (unless you're using a Pi that comes without a header)*\u003c\/li\u003e\n\u003cli\u003eCompatible with all 40-pin header Raspberry Pi models\u003c\/li\u003e\n\u003cli\u003eDimensions: 66.5 x 16.2 x 5.2mm (L x W x D, including 3.5mm jack)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003e* Note that variation in manufacturing tolerances on both headers and boards can affect the tightness of the friction fit. If you find that yours is not making a good connection, you could try bending the two rows of GPIO pins away from each other very slightly to improve the fit. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eTo ensure a robust connection, we'd suggest soldering the SHIM to your Pi's GPIO pins (or a \u003c\/span\u003e\u003ca href=\"\/en-au\/products\/2x20-pin-gpio-header-for-raspberry-pi-2-b-a?variant=1132812261\" data-mce-fragment=\"1\" target=\"_blank\" data-mce-href=\"\/en-au\/products\/2x20-pin-gpio-header-for-raspberry-pi-2-b-a?variant=1132812261\"\u003esocket header\u003c\/a\u003e\u003cspan data-mce-fragment=\"1\"\u003e) when you come to install it in your final project.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eSoftware\u003c\/h2\u003e\n\u003cp\u003eThe easiest way to get everything set up is to to use our \u003ca href=\"https:\/\/github.com\/pimoroni\/pirate-audio\" target=\"_blank\"\u003ePirate Audio software and installer\u003c\/a\u003e which configures I2S audio, as well as installing Mopidy and our custom Pirate Audio plugins.\u003c\/p\u003e\n\u003cp\u003eHere's how to get started:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eSet an SD card up with the latest version of Raspberry Pi OS.\u003c\/li\u003e\n\u003cli\u003eConnect to Wi-Fi or a wired network.\u003c\/li\u003e\n\u003cli\u003eOpen a terminal and type the following:\u003cbr\u003e\u003cbr\u003e\u003ccode\u003egit clone https:\/\/github.com\/pimoroni\/pirate-audio\u003cbr\u003ecd pirate-audio\/mopidy\u003cbr\u003esudo .\/install.sh\u003c\/code\u003e\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReboot your Pi\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eYou can find more detailed instructions here: \u003ca href=\"https:\/\/github.com\/pimoroni\/pirate-audio\/tree\/master\/mopidy\" target=\"_blank\"\u003ehttps:\/\/github.com\/pimoroni\/pirate-audio\/tree\/master\/mopidy\u003c\/a\u003e or get tons more info in our \u003ca href=\"https:\/\/learn.pimoroni.com\/tutorial\/sandyj\/getting-started-with-pirate-audio\" target=\"_blank\"\u003eGetting Started with Pirate Audio\u003c\/a\u003e tutorial.\u003c\/p\u003e\n\u003cp\u003eAlternatively, 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 line to your \u003ccode\u003e\/boot\/config.txt\u003c\/code\u003e file:\u003c\/p\u003e\n\u003cp\u003e\u003ccode\u003edtoverlay=hifiberry-dac\u003cbr\u003e\u003c\/code\u003e\u003c\/p\u003e\n\u003cp\u003eIf you're using a Pi that has an audio jack you might also need to disable onboard audio by adding a #
