ELECFREAKS Octopus 3V Laser Sensor is the laser emission electric brick in our Octopus series, the basic design is from the Octopus electric bricks, and the setting of its outlook, the PCB fixing hole, and the connectors are the same.

It is made of a laser emission chip, condensing lens, and an adjustable sleeve, which can work after powering on.
Notice: Please do not shine the eyes. The laser emits a red laser beam that usually can be seen as a red dot, but you can only see a slight red line under the condition of a frog or another medium.


The emitting principle of the laser and its special emitting process make the laser equip the features that normal light does not have: "The Three Goods" (Good monochromaticity, good coherence, and good directionality ) and "One High" (High brightness)
Support micro:bit in 3V.
