XH-M422 TPA3116D2 Class D Double Channel 50W+50W Digital Amplifier Module Stereo Power Amplifier Board

Description:
  This digital amplifier plate adopts TPA3116D2 chip.
  Configured with advanced modulation systems.
  Bluetooth transmission distance is about 10 meters.
  Transmission distance will be different due to different environment.
  If you want DIY a sound box, it's better not to use a material that has a blocking effect on the bluetooth signal.
  Its high integration reduces the number of components and integrates the natural protection circuit, including overpressure, undervoltage, overheat, DC detection and short circuit protection.
