Product Overview

Most DACs for Raspberry Pi Zero are inexpensive, copy-paste designs based on datasheets, offering mediocre performance. The miniBOSS DAC changes the game. It is the first Master DAC for the Pi Zero, designed around the PCM5122 chip with multiple engineering enhancements for cleaner, richer, and more accurate audio playback.

Instead of relying on the Pi’s CPU clock—which introduces significant jitter, especially with 44.1kHz-sampled audio—the miniBOSS uses its own dual low-jitter clocks to deliver bit-perfect playback. This “Master Mode” approach eliminates one of the Pi’s biggest audio weaknesses.

Power delivery is equally advanced. The miniBOSS isolates power into three separate channels—digital, analog, and clock—each independently filtered and regulated with LDOs for ultra-low noise. Premium NDK Japanese oscillators ensure clock stability close to high-end Crystek performance.

With careful analog stage design, film and ceramic capacitors, plus a supercapacitor for dynamic power delivery during bass-heavy passages, the miniBOSS reveals the full depth of your recordings—without artificial boosting.

Whether you’re streaming lossless audio or enjoying high-resolution music, the miniBOSS delivers exceptional fidelity on Pi Zero—and is also compatible with Pi 2, Pi 3, Pi 4, and Pi 5.
