SKU:DFR0785 (https://www.dfrobot.com/product-2363.html) (https://www.dfrobot.com/product-2363.html) Introduction This is a simple LED-illuminated switch button with a transparent cap. 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! Note: When pressed down, the module output high, and the LED lights up. Specification Operating Voltage: +3.3-5V (3.3V is recommended) Output: digital Connector: PH2.0-3P Dimension: 27×26.5mm LED Colors Available: red, yellow, green, blue, white Note: If pressed, this module will output high level and light LED up. If released, it will output low level and light LED out.
