This port provides high current drive from either the Feather Lipoly or USB port, whichever is higher. A 5V level up-shifter gives you a clean voltage signal to reduce glitchiness no matter what LED chip you're using. You can also cut power to the entire strip instantly to reduce quiescent power, thanks to a separate control transistor. \u003ca href=\"https:\/\/shop.pimoroni.com\/search?q=ws2812\u0026amp;product_type=Component\"\u003eWorks with any and all NeoPixels\u003c\/a\u003e (SK6812 \/ WS2812 family)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMAX98357 I2S 3 Watt Class D Audio Amplifier\u003c\/strong\u003e - Drive any 4-8Ω speaker, up to 3 Watts, for sound effects.
