kicad files for rsplayer music player hardware
This repository contains the hardware design files for the RSPlayer project, a high-quality audio player. The designs are created in KiCad.
This hardware design prioritizes modularity and DIY-friendliness. The goal is to provide a flexible platform where enthusiasts can easily swap components, upgrade specific subsystems (like power regulators or output stages), and experiment with different configurations. This open architecture encourages users to tweak the design, test new ideas, and continuously improve the audio performance to match their personal preferences.
