Based on the PAM8403 Class-D audio amplifier IC, this module delivers 3 watts per channel stereo output using only a 5V power supply, making it a perfect solution for DIY audio projects, portable speaker designs, and embedded sound systems. Its small footprint, high efficiency, and excellent sound quality make it a popular choice for hobbyists, students, and electronics engineers.�� Overview of XH-A156 PAM8403 Digital Stereo Amplifier BoardThe XH-A156 module is powered by the PAM8403 chip, which provides stereo audio amplification with minimal heat dissipation. Since it’s a Class-D amplifier, it works with very low power consumption, making it suitable for battery-powered devices. This board is particularly useful when you want to drive two small 4Ω or 8Ω speakers with clear, crisp audio without using bulky or power-hungry components.With USB and header pin input options, the board offers flexibility in how power is supplied. The volume control knob and dual-channel output make it user-friendly for both beginner and advanced users. Whether you’re building a Bluetooth speaker, a smart device, or integrating audio into an embedded system, this module gives you a reliable and affordable amplification solution.�� Key Features of XH-A156 PAM8403 ModuleDual-Channel Output: Provides 3W 3W stereo output, ideal for left-right speaker setups.Low Voltage Operation: Runs efficiently on 5V power from USB or header pins.High Efficiency: Class-D design offers up to 90% efficiency, reducing energy loss.Compact Design: Small and lightweight, perfect for portable projects and space-limited enclosures.Onboard Volume Control: Easily adjust sound output with the included potentiometer knob.�� Technical SpecificationsAmplifier Chip: PAM8403Operating Voltage: DC 5VOutput Power: 3W 3W (with 4Ω speakers)Load Impedance: 4Ω – 8ΩEfficiency: ≥90%Signal-to-Noise Ratio: >90dBTotal Harmonic Distortion (THD): <10%Control: Manual volume control knobInput Method: USB power or header pinPCB Size: 30mm x 25mmWeight: Approx. 5 grams⚙️ Working Principle of XH-A156 PAM8403 Amplifier BoardThis module uses the PAM8403 chip, which is a low Total Harmonic Distortion (THD) and high signal-to-noise ratio (SNR) stereo amplifier. When 5V DC power is supplied to the module, the PAM8403 boosts the audio input signal and powers two small speakers. Its Class-D topology uses pulse-width modulation (PWM) for signal amplification, which dramatically reduces heat and increases energy efficiency.The onboard volume control adjusts the analog audio input level before it is amplified. The USB or header input provides flexible power options for different project requirements.�� Applications of XH-A156 PAM8403 ModuleThis versatile board can be used in various DIY and commercial applications, including:Portable Bluetooth Speakers – Amplify sound from Bluetooth modules.DIY Audio Systems – Add audio output to Raspberry Pi, Arduino, or ESP32 projects.Voice-Activated Projects – Combine with microphones and smart controllers.Smart Gadgets and IoT Devices – Use in talking devices or interactive displays.Educational Kits – Ideal for electronics learning and prototyping.✅ Benefits of Using XH-A156 PAM8403 Digital Stereo Amplifier BoardLow Power Requirement: Runs on standard 5V power, making it compatible with USB power banks and small batteries.No Heat Sink Needed: Due to high efficiency, it stays cool even during continuous operation.Clear Audio Output: Delivers surprisingly good sound quality with minimal distortion.Plug and Play: Minimal setup – just connect power and speakers, and it’s ready to go.Affordable Solution: Cost-effective for both individual projects and bulk integration.�� What’s in the Box?1 x XH-A156 PAM8403 Digital Stereo Amplifier Board(Speakers not included)�� Integration Tips for Your ProjectsPower Supply: Use a stable 5V power source for best performance.
