Recommended Essentials:
A super-simple, slimline way to hook up a 3W speaker to your Raspberry Pi! Output punchy digital I2S audio whilst leaving your GPIO pins conveniently accessible.
SHIM is a old Yorkshire term meaning 'Hardware Shoved In't Middle' - we use it for Raspberry Pi add-ons that are designed to be sandwiched between your Pi and a HAT or mini HAT. This one has a clever friction fit header which slips handily over your GPIO pins, doesn't need soldering* and is easily removable.
The MAX98357A combined DAC / amplifier chip takes high quality digital audio from your Pi and amplifies it so it can be used with an unpowered speaker. The push-fit connectors make it straight-forward to connect up your speaker, whether it's a bookshelf or floor-standing speaker, the speaker in an old radio, or a teeny tiny mini speaker like the ones we sell here.
Because Audio Amp SHIM adds no extra bulk to your Pi it's perfect for building into a compact enclosure - you could use it to make a tiny MP3 player to play local files or stream from services like Spotify, give a vintage radio the ability to play digital radio streams or incorporate bleepy noises into your very own retro handheld. It's also a handy way to add an an audio output to your Pi Zero or Pi 400!
Features
Software
The easiest way to get everything set up is to to use Pimoroni's 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 and play local files.
Here's how to get started:
You can find more detailed instructions here: https://github.com/pimoroni/pirate-audio/tree/master/mopidy or get tons more info in Pimoroni's 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
