Stream Your Phone’s Music Wirelessly: ESP32 Bluetooth Audio Receiver Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine your favourite playlist streaming from your phone to a speaker, with no wires, no dongles, and no complex setup. This kit lets you build that exact device. Using an ESP32 development board, you’ll create a Bluetooth audio receiver that connects to any phone via A2DP, and plays crystal-clear music through a PAM8403 amplifier and a 3W speaker. It’s a simple, solder-free project that turns a pile of components into a working wireless sound system in just a few hours.

What You'll Build

A fully functional Bluetooth audio streaming device. Once assembled and programmed, your smartphone, tablet, or laptop will recognise the ESP32 as a Bluetooth speaker. You can then play music, podcasts, or audio wirelessly directly to the included 3W speaker. The circuit also exposes the amplified output, so you can easily connect the kit to larger external speakers for more volume—perfect for upgrading an old hi-fi system or creating a custom portable speaker.

What You'll Learn

• How the ESP32’s dual-mode Bluetooth and A2DP profile stream high-quality stereo audio from a phone
• How to program the ESP32 within the Arduino IDE to function as a Bluetooth audio sink
• How to wire a PAM8403 Class‑D amplifier module and match its input to the ESP32’s output
• How to use decoupling capacitors (100nF) to reduce power supply noise for cleaner audio
