### Overview

Esparagus Audio Brick is an ESP32-based compact Hi-Fi DAC and amplifier module designed as an open-hardware project that turns ordinary speakers into smart audio devices integrated with Home Assistant.

Equipped with the TAS5825M Class-D amplifier, PSRAM, and W5500 Ethernet, it delivers stable wired and wireless streaming along with high-quality output of 25W × 2.

Its DIN-rail mounting makes installation straightforward, and combining multiple units naturally enables multi-room audio or zone-based setups. It supports Music Assistant, Snapcast, and LMS (Squeezelite-ESP32), allowing users to enjoy music through Spotify Connect, AirPlay, high-quality multi-room playback, and more.
