5V operated Laser Diode module
These encapsulated laser diodes are Class IIIa 5mW, with a 650nm red wavelength. They can be driven from 5V so they're great for your embedded electronics project. You can use these for laser harps, electronic 'trip wires', laser-vision guidance, and more! Simply connect power to the red and black wires and you will be lasing in no time.
