Adafruit 36mm Square 12V Digital RGB LED Pixels (Strand of 20)

RGB Pixels are digitally-controllable lights allowing for any color setting or animation. Each robust metal pixel square contains 4 RGB LEDs and a controller chip, soldered to a PCB and enveloped in epoxy for water resistance. For enhanced durability in some applications, additional epoxy might be required.

These oversized, bright pixels have versatile mounting options, including dual metal flanges and a central 0.15"/4mm diameter hole, perfect for direct surface installation. Ideal for large-scale installations like outdoor signs, they connect via a 4-conductor cable with +12VDC, ground, data, and clock lines.

Integration is straightforward with data cascading from one pixel to the next, enabling easy strand cutting or extension. Each pixel boasts a digitally controlled 8-bit PWM LED driver, offering 24-bit color depth with 16 million shades, requiring a microcontroller for clocking. Example codes for Arduino are available to simplify adaptation for various microcontrollers.

The pixels utilize 4 x 5050 RGB LEDs with a 120-degree beam width, achieving a total max brightness of approximately 6000mcd. Note that all LEDs in a pixel are simultaneously controlled, meaning color customization is per pixel square only.

Selling as strands of 20 pixels in series, each strand includes two JST SM 3-pin connectors for seamless linking. Ensure adequate power, as high current demand may arise with multiple strands. For wiring efficiency, the two power wires are separated, and a 2.1mm terminal block adapter is advantageous for attaching a DC power supply, such as a 12V/5A source capable of supporting multiple strands depending on the current.

Driven by a constant-current, these LEDs maintain even colors throughout the strand with a stable 12V supply. Use an Arduino or similar microcontroller with any two digital pins, employing available libraries and tutorials for comprehensive guidance.
