Tip: Take a look at the table in this blogpost to see which power supply to choose for this product.

This high-quality dual channel Class-D audio amplifier board is capable of delivering 2W per channel of output power into a 4 ohm load. A PAM's PAM8803 IC offers ultra-low total harmonic distortion and noise, allowing it to deliver outstanding sound reproduction. Especially suitable for small speakers with an impedance of 4 or 8 ohms. This board can be powered by an external DC supply (4.5V to 12V) via a power port, 2.5V to 4.0V DC via a terminal block, or 2 to 3 AA batteries. Audio signal is input by a 2510 connector or 3.5 mm headphone jack, and volume control is adjustable by on-board buttons.
