The XH-A150 PAM8403 Bluetooth Amplifier Board is the ultimate "all-in-one" solution for creating ultra-portable wireless speakers. At Electrapac, we recommend this board because it combines a Bluetooth receiver, a dual-channel amplifier, and an integrated 18650 battery holder on a single compact PCB.

Product Overview

The XH-A150 is designed for simplicity. It utilizes the highly efficient PAM8403 digital amplifier chip to deliver 5W + 5W of stereo sound. Because it features a built-in battery slot and a micro-USB charging port, you can build a fully functional Bluetooth speaker without any external charging modules or complex wiring.

Key Features for Electrapac Customers

• Truly Wireless Design: The onboard 18650 battery holder means your project can be 100% portable. No need for messy external battery packs.

• Plug-and-Play Charging: Features a standard Micro-USB port to charge your 18650 battery directly on the board using any 5V smartphone charger.

• Dual-Channel High Fidelity: Despite its small size, it produces a crisp 10W total output, perfect for small rooms, desktops, or "singing machine" toy builds.

• Switchable Control: Includes an onboard power switch to preserve battery life when the speaker is not in use.

• Universal Bluetooth Pairing: Compatible with all modern smartphones, tablets, and laptops.
