Echo R1: Open-Source Music Player with High-Fidelity Audio
2025-04-24
Echo R1 is an open-hardware music player built on free software, aiming for high-fidelity audio playback. Powered by an STM32H743 processor, it boasts 32MiB of RAM and a TLV320AIC3104 audio codec supporting up to 96kHz sampling rate. The device features a 4-way D-pad, 6 multi-function buttons, dual 3.5mm jacks (headphone and line out), a replaceable battery, and expandable storage up to 2TB. Currently in its R1 prototype stage, the project is addressing known issues like an un-disableable backlight and inconsistent component labeling, while also developing a 3D-printable case.
