How to: Install Adafruit LED for Micro FPV Racing Drones - Adafruit LED Sequin For FPV Micro Racing Drones. These are good for using Line of Sight Flying for your FPV Micro Racing drone, they only show a single color and they don't have digital control, but that makes them smaller easier to use for many projects. these also will help with flying at night and for finding your FPV Micro Racing Drone in the event of an unscheduled landing or crash.
Simply connect 3 to 6VDC to the + pin and ground to the - pin, and the LED on the board will light up. You can make the LEDs fade and twinkle by using the PWM (a.k.a. analogWrite) functionality of your Gemma or Flora, or just connect directly to a digital I/O pin of a microcontroller to turn on and off. Or even skip the micro altogether, and power directly from a LiPoly or coin battery.

4mm x 9mm / .16" x .35"
2mm thick
Holes are 7mm / .28" apart
This order comes with 5 Warm White "1206 size" LEDs, matched with a 100 ohm resistor. When powered from 3.3V they draw about 5mA so you can put up to 4 or 5 in parallel on a single microcontroller pin. We also have these sequins in ruby red, emerald green, royal blue, and rose pink.
