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();
}
