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 frog or other medium.
Characteristics
The emitting principle of the laser and it's special emitting process make the laser equip the features where 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.
Easy and convenient for connection

Jargon buster
Plain-language definitions for the technical terms used above.
- 5G
- 5G is the fifth-generation mobile network standard, offering higher-speed, lower-latency wireless data than earlier 4G/LTE networks. 5G modems can move large amounts of data over cellular networks but may draw significant current and need a suitable aerial and reliable power.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
