Audio amplifier module digital 3W 5V

Small class-D amplifier with 3W output power (at 5V / 4ohm). The module is built around the amplifier-IC PAM8403 and the board has all the required support circuitry and a potentiometer for volume control and on/off. As the amplifier is digital (class-D) it has a very low current consumption and is suitable for battery powered projects.
