Software Pirate Audio: 3W Stereo Amp

Our Pirate Audio software and installer installs the Python library for the LCD, configures the I2S audio and SPI, and then installs Mopidy and our custom Pirate Audio plugins to display album art and track info, and to use the buttons for playback control.

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 tonnes more info in our Getting Started with Pirate Audio tutorial.

Notes

Note that our installer, linked above, does all of the below for you, but if you're an intrepid hacker then you might need to know this stuff!

• The push-fit connectors require you to push gently on the tab to allow the cable to be inserted / removed. Do this carefully, to avoid breaking the clip!
• The DAC can be configured by adding dtoverlay=hifiberry-dac to the /boot/config.txt file.
• There is a DAC enable pin—BCM 25— that must be driven high to enable the DAC. You can do this by adding gpio=25=op,dh to the /boot/config.txt file.
• The buttons are active low, and connected to pins BCM 5, 6, 16, and 24.
• The display uses SPI, and you'll need to enable SPI through the Raspberry Pi configuration menu.
• If you want to use these boards 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.
• Maximum wire size for the push fit connectors is 0.75mm² (1mm diameter, 18AWG)
