It’s fine to have your project generate noise, but to be heard, you need more than just a larger speaker – you need muscle! This is where this PAM8302 breakout board from Adafruit comes into play. Throw 2 to 5VDC at it, and it will amplify your mono signal into 4~8 ohm speakers with 2.5 watts of authority.

In short, it’s a small, tidy module for making your small mono signal BIG.

Specifications:

• PAM8302IC mono signal high-efficiency audio amplifier IC
• 2 to 5VDC supply voltage
• Output Power: 2.5W at 4Ω, 10% Total harmonic distortion (THD), 1.5W at 8Ω, 10% THD, with 5.5V Supply
• 50dB PSRR at 1KHz
• Filterless design, with ferrite bead + capacitors on output.
• Volume trimpot adjustment
• Built-in thermal & over-current protection
• 4mA quiescent (just sitting there, doing nothing) current draw; 1uA in shutdown mode
• Included optional 0.1″ pins and speaker wire screw-terminals
• 15x24x2mm (0.6 x 0.9 x 0.08″)
