A high-fidelity DAC expansion board for Raspberry Pi that delivers superior audio quality over the Pi's built-in 3.5mm output. Built around Texas Instruments' PCM5122 DAC chip, this board connects via the I2S interface and supports up to 384kHz sampling with 112dB dynamic range — ideal for building a dedicated network music player or HiFi streaming setup.
The board provides two output interfaces for connecting external amplifiers and audio equipment, with an LED indicator to show working status. Pair it with Volumio or another audio distribution for a complete Raspberry Pi HiFi system.

Jargon buster
Plain-language definitions for the technical terms used above.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- dynamic range
- Dynamic range describes how wide a span of values a sensor can measure, from very low to very high. For a light sensor, a wide dynamic range means it can work in dim indoor settings as well as bright sunlight without changing hardware.
- I2S
- I2S is a digital audio interface used to send sound data between chips, such as from a microcontroller to an audio amplifier or DAC. It matters if your project needs cleaner digital audio output than a basic buzzer or PWM signal can provide.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
