PIMORONI Pirate Audio: Headphone Amplifier with 3.5mm jack for Raspberry Pi

Build your own home-brew iPod Nano with Pirate Audio Headphone Amplifier by PIMORONI! It’s an all-in-one solution, with a gorgeous album art display, track info, and playback controls, for playing your local audio files (MP3, FLAC, etc) or streaming music from Spotify. The DAC and headphone amp gives you crisp digital amplified audio through your wired headphones.

PIMORONI pirate audio LINE OUT is a range of all-in-one audio boards for Raspberry Pi, with high-quality digital audio, beautifully-crisp IPS displays for album art, tactile buttons for playback control, and our custom Pirate Audio software and installer to make setting it all up a breeze.

Notes:

• The low-gain mode is recommended for most use-cases.
• 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.
