This AX22-sized module carries a bright, common-cathode RGB LED plus on-board current-limit resistors, all on a tidy 22 × 22 mm PCB. Each color channel is driven by its own active-high GPIO pin—just set the pin HIGH and the LED lights, no transistor stages or low-side drivers required—so fading or blinking is as simple as PWM from your microcontroller. It snaps straight into any AX22 backplane, making it a drop-in way to add status lighting, mood effects, or user feedback to your project. Great for dashboards, interactive art pieces, or any build that needs vivid, three-color indication with minimal wiring.
