Product Description
The XY-P15W Stereo Bluetooth Amplifier Board provides a modern, high-efficiency solution for integrating wireless audio streaming into any DIY speaker project. This compact module combines a powerful digital Class D amplifier with integrated Bluetooth connectivity, allowing users to stream music directly from their smartphones, tablets, or other Bluetooth-enabled devices.
Designed for simplicity and performance, the board operates within a wide voltage range of 8V to 24V DC, making it highly versatile for both 12V and 24V systems. It delivers a robust 10W per channel into 8Ω speakers or up to 15W per channel into 4Ω speakers (at 12V supply), offering clear, stereo sound output. The filterless Class D architecture ensures high efficiency, reducing heat generation and eliminating the need for bulky heatsinks in most applications. The board features standard screw terminals for easy power input and speaker connections. A power indicator light provides clear operational status, and intuitive audio prompts guide users through the Bluetooth pairing process. This module is an excellent choice for creating wireless speakers, retrofitting existing passive speakers with Bluetooth capability, or building portable audio systems.

Usage
This module is designed for quick integration into various audio projects. Its main function is to receive power and Bluetooth audio, then output amplified sound to speakers.
Wiring Instructions
- Power Supply: Connect your 8V to 24V DC power source to the designated power input terminals (+VCC and GND). Ensure correct polarity. A 12V or 24V DC power supply with at least 2A current is recommended.
- Speaker Output: Connect your two speakers (4Ω to 8Ω recommended) to the left and right channel screw terminals.
Bluetooth Pairing
- Power On: Upon powering the board, the power indicator LED will light up, and you will hear a voice prompt indicating the module is ready for pairing.
- Connect Device: On your smartphone or Bluetooth device, search for the Bluetooth device name “XY-P15W” and select it to connect.
- Paired Confirmation: A voice prompt will confirm successful pairing, and the indicator light may change status (e.g., stop flashing).
- Playback: You can now stream audio wirelessly to the amplifier board.
Application Scenarios
- Wireless Desktop Speakers: Building compact, wire-free computer speakers.
- Portable Boomboxes: Creating battery-powered portable speakers with Bluetooth capability.
- Motorcycle/Car Audio (12V systems): Adding simple, low-power audio amplification to vehicles or bikes.
- Smart Home Integration: Adding wirelessly controlled audio output to smart home systems.
Q: Can I use this module with a 24V power supply?
Yes, the module supports a wide input voltage range from 8V to 24V DC. A 24V supply will allow the amplifier to achieve its maximum potential power output.
Q: Is there any background noise or static when music isn't playing?
This module utilizes Class D amplification and Bluetooth 5.0, which are generally very quiet. Any noticeable noise is often “ground loop” interference caused by the power supply. Using a high-quality, regulated DC power adapter usually resolves this issue.
Q: What is the maximum speaker impedance I can use?
The board is optimized for 4Ω and 8Ω speakers. While it can handle up to 10Ω, using speakers with higher impedance will result in lower maximum volume and power output.
Q: Can I adjust the volume on the board?
This specific model (XY-P15W) relies on adjusting the volume directly from your paired Bluetooth device (smartphone, tablet, etc.). There is no physical volume knob on the standard board layout.
Q: My phone can't find the Bluetooth device name "XY-P15W". What should I do?
First, ensure the board is powered on and the indicator light is active. Try turning Bluetooth off and on again on your mobile device. If the problem persists, power cycle the amplifier board to reset its Bluetooth search mode. Ensure no other device is already paired to the module.
