Description

It is a dual channel Class D audio amplifier board capable of delivering 2W per channel of output power into 4 Ohm load. A PAM’s PAM8803 IC is used to offer ultra-low total harmonic distortion and noise, thus allowing the amplifier board to produce high-quality sound reproduction. Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Over current protection, over temperature protection and over/under voltage protection are included to extend the longevity of the amplifier board. Audio signal is input by a 2510 connector or 3.5 mm headphone jack, and volume control is adjustable by on-board buttons or external rotary encoder daughter board.
