The AA-AB32131 from Sure Electronics is a compact and efficient Class-D audio amplifier board, designed to add two channels of clear, low-power amplification to your speaker projects. With a nominal output of 2 × 2.6 watts into 4-ohm loads (or 2 × 1.5 watts into 8 ohms), this module is ideal for building portable speakers, desktop audio systems, or upgrading small multimedia enclosures where space is at a premium. Its high efficiency of 70 percent ensures minimal heat generation, making it suitable for battery-powered applications.

At the heart of the board lies the Diodes Incorporated PAM8803 amplifier IC, delivering a signal-to-noise ratio of 84 dB for clean audio reproduction. The amplifier gain is set to 23.8 dB, providing ample volume from line-level sources. Input connectivity is versatile, offering both a 3.5 mm jack and solder-pad terminals for flexible integration. Speaker outputs are via screw terminals, simplifying wiring to your chosen drivers. The board measures just 72 by 55 by 18 mm, with mounting holes spaced 62 by 45 mm apart for secure installation. Whether you are prototyping a custom sound system or refreshing an existing build, this booster module offers reliable, space-saving performance.
