If you are considering building an audio player into your next project, then you should take a look at the simple-to-implement Adafruit I2S 3W Class D Amplifier Breakout board. It’s a surprisingly powerful little mono amp that’s able to send 3.2 watts of power to a 4 ohm impedance speaker. And it works with I2S audio, so there is less noise, making the sound output much cleaner. It also features selectable gain, click and pop reduction, and best of all, it’s very affordable. If you want clean sound, grab this board!
They give the sensor a 10/10, saying “You can’t beat the price of this little amp..”
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.
