OPSCO SK6805MINI Built-in IC 2020/3528 SMD RGB LED Chip - 256 Grade Full Color Addressable Pixel Light with 4-Pin NZR Interface

Its compact footprint (available in 2020, 2427, 3528 and other mini packages) makes it ideal for high-density LED strips, pixel screens, and intricate decorative lighting. With a wide operating voltage of 3.7V–5.5V, a constant current drive of 5mA per channel, and a refresh rate of up to 2kHz, the SK6805MINI ensures stable, flicker-free performance. Whether you're building smart home accents, stage lighting, or DIY Arduino/ESP32 projects, this chip offers a reliable, easy-to-use solution for brilliant, dream-color lighting effects.

• All-in-One Mini Design: Integrates RGB LED and control IC into a single compact SMD package (as small as 2.0×2.0mm), perfect for space-constrained, high-density lighting layouts.

• Vivid 24-Bit True Color: Delivers 256 grayscale levels per channel (R/G/B), delivering over 16.7 million colors and smooth gradient effects for stunning visual displays.

• Single-Wire Cascading Control: Uses NZR single-line communication; control hundreds of LEDs with just one MCU I/O pin, significantly simplifying wiring and PCB design.

• Wide Voltage & Stable Drive: Operates on 3.7V–5.5V with a built-in constant current output of 5mA per channel, ensuring consistent brightness and color uniformity even with voltage fluctuations.

• Fast Refresh & Easy Integration: Supports up to 2kHz PWM refresh rate for flicker-free performance; fully compatible with Arduino, FastLED, ESP32, and other mainstream development platforms.
