KY-008 Laser Transmitter Module Features This Laser module emits a small intense focused beam of visible red light.  The operating voltage is 3-5 V and the required current is 40mA. Note Since the required current is 40 mA and the Arduino pins can supply this current, this module can be connected directly to Arduino. If need be more than 40mA, direct connection to Arduino will damage the Arduino. In that case, you need to use a laser driver to connect the laser module to Arduino. ...
