The XD-58B HXJ8002 Mini Audio Amplifier Module is a compact and efficient mono audio amplifier board based on the HXJ8002 IC. Designed for low-power applications, it delivers up to 3W of output power at 5V, making it ideal for driving small speakers in portable audio projects, toys, buzzers, and embedded electronics. With its Class AB amplifier architecture, this module provides clean, low-distortion audio output while operating at low voltage and consuming minimal power. Its small size and simple 3-pin interface make it perfect for integration with microcontrollers like Arduino, ESP32, or Raspberry Pi. Key Features Chipset: HXJ8002 (Class AB mono audio amplifier) Operating Voltage: 2V – 5.5V DC (optimal at 5V) Output Power: Up to 3W at 5V (with 4Ω speaker) Interface: 3-pin (VCC, GND, AUDIO IN) Compact Size: Fits easily into space-constrained projects Low THD (Total Harmonic Distortion): Clear sound with minimal noise Short-circuit and thermal protection Applications: DIY speakers, smart toys, sound effects modules, voice playback systems
