XY-P15W Stereo Bluetooth Power Amplifier Board

XY-P15W Stereo Bluetooth 5.0 Power Amplifier Board is an incredibly compact, highly efficient wireless audio amplification module perfectly tailored for DIY audio enthusiasts and custom speaker builders. Operating as a Class-D digital amplifier, this small but mighty board merges high-fidelity audio processing with an advanced Bluetooth 5.0 receiver to stream flawless, low-latency sound directly from your smartphone or tablet. Consequently, creators eagerly adopt this module to breathe new life into vintage passive speakers or to construct custom, portable wireless boomboxes. The module flexibly supports a wide voltage range from 8V to 24V, allowing it to adapt effortlessly to various battery packs and power supplies while delivering up to 30W of power per channel. Furthermore, its onboard rotary potentiometer not only provides smooth volume adjustment but also functions as a convenient physical power switch. Therefore, whether you are engineering a hidden multi-room audio setup or upgrading a desktop stereo, this amplifier board provides exceptional acoustic power without the need for bulky external receivers.

Key Features:

• Bluetooth 5.0 Connectivity: Offers a stable, low-latency wireless connection up to 15 meters, therefore minimizing frustrating audio dropouts and syncing perfectly with modern smart devices.
• Wide Voltage Support: Accepts a broad DC input from 8V up to 24V, ensuring flexible compatibility with standard 12V adapters, lead-acid batteries, or lithium-ion packs.
• Integrated Volume Knob: A smooth rotating potentiometer easily adjusts output volume and clicks off to shut down the amplifier entirely.
• Multi-Impedance Compatibility: Safely drives a wide variety of speaker coils, accommodating 4Ω, 8Ω, and 16Ω setups depending on your chosen input voltage.
• Comprehensive Protection: Equipped with reverse power protection, short-circuit protection, and thermal self-recovery to consequently prevent catastrophic hardware failure during unexpected electrical faults.

Technical Specifications:

• Operating Voltage (V_IN): 8V to 24V DC (2.0A or higher recommended; DO NOT exceed 26V)
• Maximum Output Power: Up to 30 W + 30 W (at 8 Ω load, 24V supply, requires external heatsink)
• Typical Output Power: 15 W + 15 W (at 8 Ω load, 16V supply)
• Supported Speaker Impedance: 4 Ω (8-12V max), 8 Ω (8-24V), 16 Ω (8-24V)
• Bluetooth Version: v5.0 (Backwards compatible)
• Transmission Distance: Up to 15 meters (Unobstructed line of sight)
• Amplification Class: Class-D Stereo

Mechanical Specifications:

• Board Material: Multi-layer FR4 Fiberglass PCB
• Cooling Requirement: Functions normally under 20W/channel; however, an added aluminum heatsink is strictly required if operating at the maximum 24V/30W limit.
• Connector Interfaces: 5.5×2.1mm DC barrel jack for power, combined with standard screw terminal blocks for speaker wiring.
• Operating Range: −40°C to +85°C (at 0% to 95% relative humidity)

Dimensions:

• Module Length: ≈ 50.0 mm
• Module Width: ≈ 35.0 mm
• Module Height: ≈ 14.0 mm

Pinout and Wiring:

• DC In (Barrel Jack): Plug in a standard 5.5×2.1mm DC power adapter (12V-24V favored for most speakers).
• L_OUT+ / L_OUT- (Terminals): Terminate your Left channel speaker wires securely into these screw clamps.
• R_OUT+ / R_OUT- (Terminals): Terminate your Right channel speaker wires securely into these screw clamps.
• Wiring Note: Ensure your power supply voltage natively matches your speaker’s impedance limitations, otherwise pushing a 4Ω speaker with 24V will instantly trigger thermal shutdown.
