A simple, no-cost, no-soldering modification to your Adafruit STEMMA Speaker delivers noticeably more punch from this tiny package. “Speakers are weird animals!”
So why are they assembled this way rather than face down? It gives you more options. You might want to stick the oval to a still larger resonant surface, or inside an enclosure. Also the back side can take a few stickings/un-stickings, but the oval side is more permanent.
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.
