ESPHome Louder ESP32 Media Player
Custom ESPHome component and configuration for the Louder ESP32 Rev-E board, enabling TAS5805M Class-D amplifier control as a Home Assistant media player with I2S audio output.
Custom ESPHome component for the Sonocotta Louder ESP32 board (Rev-E) featuring the TAS5805M Class-D audio amplifier DAC from Texas Instruments.
What It Does
This project provides a complete ESPHome YAML configuration and custom C++ component (louderesp32.h) that initializes and controls the TAS5805M DAC via I2C, enabling the Louder ESP32 to function as a networked media player within Home Assistant.
Key Features
- Custom TAS5805 driver class managing amplifier initialization via GPIO pin 33
- I2C communication with DAC at address 0x2D
- I2S audio output (LRCLK GPIO25, BCLK GPIO26, DOUT GPIO22)
- Octal PSRAM mode at 80MHz for audio buffering
- Power consumption under 20W at full load, 1.1W standby
- Enable/disable switch exposed to Home Assistant
Setup
The project includes two main files:
louderesp32.yaml— ESPHome device configurationlouderesp32.h— Custom C++ component for TAS5805M control
Flash via ESPHome dashboard or CLI. The board appears as a media player entity in Home Assistant.
