NEW GUIDE: Adafruit STEMMA Audio Amp #STEMMA #Audio #AdafruitLearningSystem @Adafruit
TheAdafruit STEMMA Audio Ampis a super small mono amplifier is surprisingly powerful – able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, it’s very efficient (over 90% efficient when driving an 8Ω speaker at over half a Watt) – making it perfect for portable and battery-powered projects.
This board is a simplified version of our breadboard-friendly Adafruit Mono 2.5W Class D Audio Amplifier board. This version is designed to be ‘plug and play’ – with no soldering required. You can input the audio via the JST-PH 3 Pin connector – such as a pin header cable or one with alligator clips. The trade-off is that this board doesn’t have differential inputs, instead the audio inputs are referenced to the power/signal ground wire.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
