The module power supply ground and signal ground are separated, and there is a separate resistance, which is more convenient for different power amplifiers to choose to use (see the r18/4.7r ohm resistance on the board). Now it has been shipped with 4.7 ohm connection. Some power amplifiers have noise. It is recommended to use a separate power supply to supply power to the decoding board. If it is the same power supply as the power amplifier, please first cancel the r18/4.7 ohm resistance of "agnd" and "GND" connected to the audio output ground and power ground of the decoding board
