A 100-pack of individual NeoPixel RGB 5050 LEDs with integrated WS2812B-compatible driver chips. Each 5mm × 5mm LED includes ~18mA constant-current drive per channel, so colour remains consistent regardless of voltage variation — no external resistors needed. Power with 5VDC.

These are the 4-pin (WS2812B) variant with built-in reverse polarity protection. They are chainable — connect the data output of one LED to the data input of the next. Requires a real-time microcontroller (AVR, Arduino, PIC, etc.) running at 8MHz or faster. Not compatible with interpreted controllers or Linux-based microcomputers for direct driving.
