Integrating Bluetooth reception and a digital amplifier, it can directly drive 4-16Ω speakers with a wireless range of up to 15 meters (line-of-sight) . The module utilizes a Class-D architecture with over 90% efficiency and features multiple protection mechanisms including reverse polarity, short circuit, and thermal protection. An onboard volume/playback control knob allows for easy operation, and the module can be paired by searching for "XY-P15W" on a smartphone. It is widely used in DIY Bluetooth speakers, car audio upgrades, portable PA systems, home theaters, and multimedia classrooms.

XY-P15W Bluetooth Digital Amplifier Module Key Features

Efficient Class-D Amplifier & Quality Bluetooth Chip: Powered by the TI TPA3110 Class-D amplifier chip and the JL AC23C0 Bluetooth chip, achieving ≥90% power conversion efficiency for high-fidelity audio output and low heat generation.

Wide Voltage Supply & Flexible Adaptation: Supports DC 8-24V wide input (12V or 24V recommended). Input voltage must not exceed 26V. When driving 4Ω speakers, supply voltage must be under 12V; when driving 8Ω or 16Ω speakers, supply voltage can be up to 24V.

Bluetooth 5.0 Wireless Connectivity: Equipped with Bluetooth 5.0, offering a transmission range of up to 15 meters (line-of-sight) . It enters pairing mode upon power-on and can be connected by searching for "XY-P15W" on a smartphone with no pairing code required.

Multiple Protection Mechanisms: Built-in reverse polarity protection, short circuit protection, and self-resetting thermal protection effectively prevent damage from wiring errors or abnormal operating conditions.

Convenient Operation & Connection: Features a semicircular control wheel: rotate to adjust volume and press to play/pause. Uses screw terminals for direct speaker wire connection with no 3.5mm headphone jack.

FAQ:

1. What is the XY-P15W?
The XY-P15W is a stereo digital amplifier module with built-in Bluetooth 5.0, combining Bluetooth reception and amplification to turn passive speakers into Bluetooth speakers.

2. What are the key specifications?

Operating Voltage: DC 8-24V

Bluetooth Version: 5.0

Transmission Distance: Up to 15 meters (line-of-sight)

Speaker Impedance: 4Ω, 8Ω, 16Ω

Module Size: Approx. 50x33x12mm

3. How do I pair it with my phone?
After power-on, the blue LED will flash quickly, and the module enters Bluetooth mode. Search for "XY-P15W" on your phone and tap to connect. No pairing code is required. The LED will stay solid once connected.

4. How do I control volume and playback?
The module features a half-round knob. Rotate it to adjust the volume and press it to play/pause.

5. What power supply do I need?
You need a DC 8-24V power supply, such as a 12V or 24V adapter. The power supply should provide at least 2A, and the input voltage must never exceed 26V.

6. What speakers should I use?
It is recommended to use speakers with a rated power of 30W or more. Choose impedance based on supply voltage: keep voltage under 12V for 4Ω speakers; under 24V for 8Ω or 16Ω speakers.

7. How does output power relate to voltage and impedance?
Output power increases with voltage. For example: approx. 16W×2 at 12V/4Ω; up to 30W×2 at 24V/8Ω.

8. When do I need to add a heatsink?
A heatsink is required when output power exceeds 20W×2 to prevent overheating damage.

9. What protection features does it have?

Reverse Polarity Protection

Short Circuit Protection

Self-recovering Overheat Protection

10. What are the key precautions?

Avoid Interference: Keep away from Wi-Fi routers and other sources

Speaker Wire Length: Keep it under 1 meter

ESD Protection: Discharge static from your hands before touching the board

Troubleshooting: Check power if LED is off; move away from router if "XY-P15W" isn't found; check source, speaker, or power for noise; check for overheating or unstable Bluetooth signal for intermittent playback.
