## Description

The Adafruit STEMMA Audio Amp is a compact mono Class D amplifier based on the PAM8302 chip, delivering up to 2.5W into 4 Ω speakers from a 2.0–5.5V DC supply. With over 90% efficiency at half a watt into 8 Ω, it's ideal for portable and battery-powered audio projects. This plug-and-play STEMMA version requires no soldering — audio input connects via a JST-PH 3-pin connector. The output is bridge-tied and drives speakers directly through a filterless design with ferrite bead and capacitor filtering. A built-in trim pot lets you adjust volume down from the default 24 dB gain. Key Features PAM8302 Class D Amplifier – 2.5W at 4 Ω or 1.5W at 8 Ω (10% THD, 5.5V supply) Wide Voltage Range – 2.0–5.5V DC operation High Efficiency – Over 90% at 0.5W into 8 Ω Volume Trim Pot – Adjustable from default 24 dB gain Thermal + Overcurrent Protection – Built-in safety features Low Quiescent Current – 4 mA active, 0.5 mA shutdown 50 dB PSRR – At 1 kHz for clean audio JST-PH Audio Input – No-solder STEMMA connection (ground-referenced, not differential) Filterless Design – Ferrite bead + capacitors on output Ideal For Battery-powered audio projects Portable speakers and sound effects Interactive exhibits and installations Wearable audio devices Package Contents 1× STEMMA Audio Amp breakout board (PAM8302) 1× Header strip 1× 3.5 mm screw terminal block for speaker connection Note: Speaker not included — use any 4 Ω or greater impedance speaker. The output is bridge-tied and must connect directly to a speaker, not to another amplifier. Terminal block colour may vary (blue or black).
