Individually addressable RGB LEDs with an SPI-style data and clock interface let each pixel be set independently, making them ideal for animated lighting, matrix displays, wearable effects, signage and accent illumination. Strips and flexible panels scale from a handful of pixels to hundreds, supporting smooth gradients and low-latency updates.
Key attributes include pixel density, form factor (strip or panel), 5 volt supply compatibility, chaining length and per-pixel PWM resolution, all of which influence brightness, colour fidelity and heat management. SPI control simplifies timing for microcontroller projects, while solder pads, power distribution and mechanical flexibility affect ease of integration and long‑run reliability.
