DFR0789

SKU:DFR0789 (https://www.dfrobot.com/product-2350.html) (https://www.dfrobot.com/product-2350.html) Introduction This is a simple LED-illuminated self-lock switch button. It’s just like a basic switch button, but it lights up color(red / yellow / green / blue / white) when pressed down, which gives you visual feedback. These little buttons can be used with micro:bit to realize various fun interactive projects, such as, switch, backlight keyboard, music player panel, recording control panel, etc. Specification Operating Voltage: +3.3-5V (3.3V is recommended) Output: digital Connector: PH2.0-3P Dimension: 27×26.5mm Colors Available: red yellow green blue white Colors Available: red, yellow, green, blue, white Note: The module comes with self-lock function. When the button is pressed down, the module outputs High, and the LED lights up. When being pressed again, the module outputs Low and the LED turns off.
