PIMORONI Pirate Audio Line-out for Raspberry Pi

• 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.
