Keyboard Key with an Addressable LED

Keyboard Key with an Addressable LED

AX22-0027

Click it, see it. This AX22-sized board seats a mechanical switch and tucks a tiny  “NeoPixel” LED beneath it, giving you crisp tactile input and full-colour feedback from the same 22 × 22 mm square. Comes with a built-in debounce circuit the switch and an active-low GPIO read. Drop it into any AX22 backplane to add per-key lighting, mode indicators, or game-style bling with a single digital pin and a handful of library calls in Arduino, MicroPython, or MicroBlocks.

Arduino Example Snippet 

#include <Adafruit_NeoPixel.h>

#define BUTTON_PIN 1
#define NEOPIXEL_PIN 14

#define NUM_PIXELS 1   // assuming only one NeoPixel

Adafruit_NeoPixel strip(NUM_PIXELS, NEOPIXEL_PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  pinMode(BUTTON_PIN, INPUT_PULLUP);
  strip.begin();
  strip.show(); 
}

void loop() {
  int buttonState = digitalRead(BUTTON_PIN);

  if (buttonState == LOW) {
    strip.setPixelColor(0, strip.Color(255, 0, 0)); // Red
    strip.show();
  } else {
    strip.setPixelColor(0, strip.Color(0, 0, 0)); // Off
    strip.show();
  }
