Make your own ultra small or high-density smart LED arrangement with the same kind integrated LED that is used in our NeoPixel strip and pixels. This atomic-scale tiny 1111 (1.1mm x 1.1mm) RGB LED is designed to be surface-mount soldered and is the most compact way possible to integrate multiple bright LEDs into a design. Seriously, these are unbelievably small: usually you’ll see the 5050 LEDs that are 20x larger, or the 3535 ‘mini’ NeoPixels that are 10x larger.
The driver chip is inside the LED and has ~5 mA constant current drive, so the color will be very consistent even if the voltage varies, and no external choke resistors are required making your design minimal. Power each one with about 5 VDC, and you’re ready to rock. We’ve used 3.3V power and it isn’t as bright but still functions fine.

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.
