Brief Introduction:

This is a high-quality dual-channel class-D audio amplifier board capable of delivering 2W per channel of output power into a 4Ω load. It employs PAM’s PAM8803 IC which offers 64-step digital volume control and low THD+N, allowing it to produce high-quality sound reproduction. It’s especially suitable for small speakers. This amplifier board can also be used to drive passive 4Ω or 8Ω speakers.
Three kinds of unique design make this product a perfect "Class D" architecture: (1) This board can be either powered by wide DC voltage (DC4.5V to12V) via a power port or powered by 2 to 3 AA batteries or DC2.5V to 4.0V via a terminal block. (2) Audio signal can be input via 2510 connector or 3.5mm headphone jack. (3) Volume control is available via on-board buttons or an external rotary encoder daughter board.

Features:

1.2W @ 8Ω, < 10.0% THD+N
2.0W @ 4Ω, < 10.0% THD+N
