Its ultra-small 3.2×1.0mm footprint and EC3210 PCB bracket design make it perfect for space-constrained applications like smart wearables, mini displays, and decorative lighting. With a 4kHz PWM refresh rate and 2000V ESD protection, it ensures flicker-free, reliable operation from -40°C to +80°C. Choose SK6805-EC3210 for uncompromised color precision in the tiniest form factor.
Ultra-Compact 3210 Package: Measures just 3.2×1.0×1.48mm, ideal for miniature electronics, wearables, and high-density pixel arrays.
Built-in Smart IC: Integrates driver, oscillator, and data reshaping in one chip—no external components needed, simplifying PCB design.
Low Power 5mA Version: Optimized for energy-sensitive projects; significantly lower current draw than standard 12mA SK6812 variants.
True 24-bit Color & 4kHz PWM: Supports 256 grayscale levels per channel with a 4kHz refresh rate for smooth, flicker-free visual effects.
Wide Compatibility & Robustness: Single-wire 800kbps protocol works with Arduino/ESP32; features 2000V ESD protection and -40°C to +80°C operation.
The SK6805-EC3210 is a 4-pin, 3210-sized SMD LED with an embedded control IC. It combines a precision internal oscillator, a programmable constant current output driver, and a single-wire data interface to deliver individually addressable RGB lighting. Each device acts as one pixel in a cascaded chain, automatically forwarding data to the next LED.
Communication: Single-wire return-to-zero code, 800 kbps
Color depth: 24-bit (8-bit per channel, 16.7M colors)
PWM frequency: 4 kHz
Input voltage: 3.7V – 5.5V DC (typical 5V)
Static current: ~0.25 mA
Operating temperature: -40°C to +80°C
ESD (HBM): 2000V
Package options: EC3210R (round lens), EC3210F (flat lens)

Data is transmitted as 24-bit packets (order: G7–G0, R7–R0, B7–B0). The first LED reads its 24 bits and passes the remainder to the next via DOUT. A low-level reset signal (>50µs) latches data and updates outputs.
