Enjoy music, enjoy life.

This PCB is a compact low-noise linear power supply intended for audio applications (DACs, clocks, analog output stages, I/V converters, preamps, active filters, etc.). The main goal is to obtain a very clean DC rail with low 100/120 Hz hum and reduced high-frequency “rectifier dirt” coming from the bridge.

LedBox V3 is an ultimate, sound-reactive LED controller, compatible with 5-12V addressable LED strips (WS281x, SK6812, etc.), supporting 3-(data) and 4-(data/clock) wire signal protocols. Whether you prefer a plug-and-play solution, or you are a maker that loves tinkering with hardware, it offers the best of both worlds.
