Pimoroni Pirate Audio: Turn a Raspberry Pi into an iPod replica with Spotify integration thanks to a high-quality amplifier, DAC and display
Apple may have killed all but the iPod Touch of its iconic iPod range, but that does not mean that media players have died off completely. Sony still makes products like the NW-A45, for example, while there are plenty of lesser brands churning out MP3 players.
Alternatively, you could make your own. Now, you can even create one using a Raspberry Pi thanks to the Pirmoroni Pirate Audio. Sold as a headphone amp, the unit is an all-in-one solution that not only has a headphone amp and 3.5 mm jack but also a 1.3-inch display and a DAC. Specifically, the Pirate Audio incorporates the following:
- PAM8908 headphone amplifier
- Low-gain/high-gain switch (high-gain boosts to 12 dB)
- PCM5100A DAC
- 3.5 mm stereo jack
- 1.3-inch colour IPS LCD - ST7789 driver (240 x 240 px)
- Four physical buttons
According to the manufacturer, the Pirate Audio can output amplified 24-bit/192 kHz digital audio via I2S. Its Texas Instruments PCM5100A DAC offers a dynamic range of up to 100 dB, which also applies to its signal-to-noise ratio. Meanwhile, the PAM8908 headphone amplifier delivers up to 25 mW per channel. The 65 x 30.5 x 9.5 mm board is compatible with all 40-pin header Raspberry Pi models, although its dimensions mirror those of the Model Zero.
