KY-008 650nm Laser Transmitter Module, 5V

The KY-008 Laser Transmitter Module generates a visible 650 nm red laser beam using a standard 5 V DC power source. It is an accessible component for students, educators, and hobbyists building optical tripwires, light communication systems, or precision targeting experiments. With its lightweight and compact form factor, it easily integrates into breadboard and microcontroller projects.

Visible optical output

The module emits a 650 nm wavelength laser beam powered by a 5 V supply. It provides a focused light source suitable for simple optical experiments and line-of-sight sensing.

Compact form factor

Weighing only 2.2 g and measuring 15 x 24 mm, the board fits easily into tight enclosures, robotics frames, and prototype builds without adding noticeable weight.

Receiver compatibility

This transmitter is compatible with complementary laser receiver modules to form complete beam-break detection and optical transmission circuits.
