XH-M181 PAM8610 Stereo Amplifier Board – 2x15W Class D

PAM8610 Dual Channel Stereo Digital Audio Amplifier Module is a 30W dual channel stereo, Class D (PWM modulation type) digital amplifier, which is based on the PAM8610 integrated chip. It has a DC adjustable volume, which achieves low THD+N (0.1%), low EMI, and good PSRR result , so it’s an ultra low cost and space. Because of adapting the low pass filter in the output, effectively reduces high-frequency noise and spike interference While amplifying, some interference source devices such as  are not being placed or used near this module.

Note:
Do not short-circuit the audio output to each other or shorted to ground
