Simply connect VCC to 5V, GND to ground, and signal pin (if any) to a digital I\/O. No additional components required for basic operation.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect red wire to 5V, black to GND. For modules with a third wire (enable\/signal), connect to a digital pin and set HIGH to turn on the laser. Do not exceed 5V; a current-limiting resistor is built in. Avoid direct eye exposure.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
