**Basic Parameters:** - **Color:** Full color - **Waterproof Rating:** IP20 (non-waterproof), IP65 (epoxy waterproof), IP67 (casing waterproof), IP68 (fully waterproof) - **Wavelength:** 620–630 nm (red), 520–525 nm (green), 465–470 nm (blue) - **Light Intensity:** 500–600 mcd (red), 900–1200 mcd (green), 250–310 mcd (blue) - **Luminous Flux:** 1.68 lm (red), 3.2 lm (green), 0.84 lm (blue) - **Dimensions:** 5000 x 12 mm - **Weight/Volume:** 300g - **Illumination Angle:** 120° - **Operating Voltage:** DC 5V - **Power Consumption:** 10W/m - **LEDs per Meter:** 32 LEDs/m - **IC Model:** WS2801 - **ICs per Meter:** 32 ICs - **Control Mode:** SPI, with data (DAT) and clock (CLK) lines **Control Principle:** Each IC controls one LED, forming a loop or group. The controller sends signals through the FPCB to the ICs, which then manage the LED strip’s behavior, such as blinking, chasing, jumping, or rotating. You can write custom code to achieve different lighting effects based on your needs. The WS2801 chip has a built-in signal regeneration function. After detecting a rising edge, it generates an internal 300ns high-level pulse to serve as the clock signal for data transmission. At a frequency of 2MHz, up to 2048 points can be connected in series, and the frame rate can reach 30Hz or higher. The grayscale data structure of the WS2801 is shown in Figure 2:Figure 2
The data transmission timing for the WS2801 is illustrated in Figure 3:Figure 3
Since the DragonBoard 410c operates at 1.8V and the WS2801 requires 3.3V, a voltage conversion chip is necessary between the board and the LED strip. The wiring diagram between the DragonBoard 410c and the LED strip is shown in Figure 4:Figure 4
