Description

The Pimoroni Pico Audio Pack is designed to bring robust audio functionality to your Raspberry Pi Pico projects. Utilizing a high-quality PCM5100A I2S DAC, this add-on board delivers up to 32-bit, 384KHz stereo audio. It offers dual output options: a 3.5mm line-out connector for unamplified audio, ideal for connecting to external amplifiers or powered speakers, and a 3.5mm headphone jack that provides amplified stereo sound through its integrated PAM8908JER headphone amplifier, featuring a switch for gain adjustment (low/high).

This versatile audio pack enables a range of creative applications, from generating unique noises for lo-fi synthesizers to transforming your Pico into a custom USB sound card when paired with another device. It’s also perfect for adding sound effects or short audio clips to embedded projects. While I2S audio for Pico/RP2040 is not currently supported in MicroPython, it is fully compatible with CircuitPython, offering developers a flexible platform for audio experimentation.

Key Features

  • PAM8908JER stereo headphone amp for robust audio output.
  • Adjustable headphone amp gain switch (low/high) for tailored audio levels.
  • Pre-soldered female headers for direct, solderless connection to Raspberry Pi Pico.
  • Seamlessly compatible with the Raspberry Pi Pico platform.
  • Fully assembled and ready for immediate use.
  • Requires no soldering if your Pico already has header pins attached.

Applications

  • Developing lo-fi synthesizers and audio generators with Raspberry Pi Pico.

Frequently Asked Questions

What DAC chip does the Pico Audio Pack use and what are its capabilities?

The Pico Audio Pack utilizes a PCM5100A I2S DAC, capable of outputting high-fidelity stereo audio at up to 32-bit, 384KHz. This ensures excellent sound quality for various audio applications on the Raspberry Pi Pico.

Which programming environments support the Pico Audio Pack?

While I2S audio is not currently supported in MicroPython for the RP2040, the Pico Audio Pack is fully compatible with CircuitPython. Raspberry Pi's experimental C/C++ examples also provide support for its functionality.

What are the primary audio outputs available on this board?

The board offers two main audio outputs: a 3.5mm stereo line-out jack for unamplified audio, suitable for external amplifiers, and a 3.5mm stereo headphone jack, providing amplified sound via its PAM8908JER chip with adjustable gain.

Does the Pico Audio Pack require soldering for installation?

No, the Pico Audio Pack comes fully assembled with pre-soldered female headers. This allows for direct, solder-free attachment to a Raspberry Pi Pico board, provided the Pico itself has header pins attached.

Which Raspberry Pi Pico pins are used for I2S audio data?

The Pico Audio Pack uses I2S_DATA, I2S_BCK, and I2S_LRCK for audio data reception. For compatibility with Raspberry Pi's experimental examples, PICO_AUDIO_I2S_DATA_PIN and PICO_AUDIO_I2S_CLOCK_PIN_BASE should be defined as 9 and 10, respectively.
