Digital Audio Amplifier Module (DC 12?24V) with Bluetooth

The Bluetooth power amplifier board is a compact, digital 2.0-channel stereo amplifier module. It delivers a maximum output of 2x 50 watts and operates within a flexible voltage range of DC 12V to 24V. Thanks to Class-D efficiency, it offers high output power with minimal heat generation.
  • Power Supply: Connect a DC power supply to the designated terminals (labeled +VCC / -GND). Ensure correct polarity (+/-) to avoid damaging the module.
  • Speakers (Audio Out): The board features two separate outputs for stereo sound (SPL / SPR).

  • Bluetooth: Upon power-up, the board automatically enters Bluetooth pairing mode. Search for a new Bluetooth device on your smartphone or PC (often named after the chip or "Xinyi," etc.) and pair with it.

Actual output power depends directly on the voltage and current of your chosen power supply, as well as the impedance (ohms) of your speakers:
  • 12V Power Supply: Provides lower maximum volume (approx. 2x 15W at 4 ohms). Ideal for small PC speakers or for use in a car or motorhome.
  • 24V power supply: Extracts the full 2x 50W from the chip (with 4-ohm speakers). The power supply should deliver at least 3A to 5A (amperes) to prevent audio distortion at high volumes or the module from shutting down.
