This article provides a guide on building a DIY high-end Bluetooth speaker in only 30 minutes using an ESP32 and simple hobbyist components. Using a LILYGO T-Display board, which supports the Bluetooth Classic protocol required for A2DP audio streaming, the project pairs with a MAX98357A module to act as a digital-to-analog converter and amplifier. The setup uses the I2S interface for audio transmission and can even display track information and connection status on the onboard TFT screen. It is an excellent, quick project for electronics enthusiasts looking to repurpose spare parts into a functional, polished audio device.
