650nm Red Laser Diode Module pH Sensor 2×4 pin through-holes for 2×650nm Laser Diode Module The 650nm Laser Diode Module encapsulated laser diodes are Class IIIa 5mW, with a 650nm red wavelength. They can be driven from 2. 8V to 5. 2V 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. Get a laser pointer atop your gun Sam! Or make an
