The component U5 in your schematic is a WS2812-2020, which is an RGB LED with integrated control circuitry. Here's a breakdown of its functions:
  • RGB LED: The WS2812-2020 integrates a red, green, and blue LED in a single package, allowing it to produce a wide range of colors. The color and brightness of each LED can be controlled individually.
  • Integrated Control Circuitry: The WS2812-2020 includes a control IC that enables individual control of each LED by cascading multiple LEDs in a daisy-chain configuration. It requires only one data line to provide control data for the entire chain of LEDs.
  • Data Input (DI) and Output (DO): U5 receives data from a control source through the DI pin and passes data to the next LED in the chain through the DO pin, allowing multiple LEDs to be controlled via a single data line.
  • Power Supply: The WS2812-2020 operates from a DC voltage supplied to the VDD pin, typically 5V, and a ground connection (GND).
In the context of your project, these RGB LEDs are used for per-key RGB lighting, likely providing customizable lighting effects for the keys on your macro keyboard.
