This high-density LED strip has a length of 0.5 m and contains 72 RGB LEDs that can be individually addressed using an easy-to-control SPI interface, allowing you full control over the color of each RGB LED. The flexible, waterproof strip runs on 5 V and can be chained with additional SK9822 strips to form longer runs or cut apart between each LED for shorter sections.
These flexible RGB LED strips based on the SK9822 LED/driver IC are an easy way to add complex lighting effects to a project. Each LED has an integrated driver that allows you to control the color and brightness of each LED. The SK9822 has constant current control, so voltage drops caused by the resistance in long power connections have little effect on the SK9822’s color and brightness as long as the voltage stays above 3.5 V.
In contrast to the SK6812 used in some of our other similar LED strips, which use a specialized one-wire control interface and require strict timing, the SK9822 uses a standard SPI interface for control (with separate data and clock signals) and has no specific timing requirements, making it much easier to control. Another useful feature of the SK9822 is an additional 5-bit brightness control register that allows you to dim your LED strip while still having 24-bit color control. See below for a more detailed comparison of the SK9822 and SK6812.
These SK9822-based LED strips work as a drop-in replacement for our older APA102C-based strips in many applications. However, due to slight color differences, we generally do not recommend using the SK9822 and APA102C together in the same project. Also, due to a slight difference in the protocol, you might have to update your code to handle the SK9822. See below for a more detailed comparison of the SK9822 and APA102C.
