    Great little module, although the markings area off. Gnd gets +5v S to Supply 0v for a permanent on state. The focus mechanism works quite well for a wide beam if needed.

    It's a great module but the laser itself is not really aligned with the board . It goes a little bit on the right ! That's the right way to connect it to your arduino : "S" : signal _connected to a digital pin "-" : Connected to the ground Middle pin : connected to 5 volt
