Banggood

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.

good, but gnd and 5v are mixed

fast delivery as usual, very good quality and appearance.. I used it in many applications and it worth every penny..

these work great and taste amazing

Very good quality

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

good quality It will be tested soon

This is very good priced item. I suggest buying it. Delivered fast and very useful.

Very small and cheap module for arduino.

excelentess parts, good quality, arrived well packed, Highly recommend !!
