but nothing too bad. what is marked with (-) should go to pwm pin as signal, middle pin should go to ground from external power source (MB102 is great for that!) and what is marked as (S) becomes + from external 5v power. once this is connected laser is nice and precise.

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
