Adjustable Focus 650nm-300 Red Laser PWM Laser lamp

Adjustable focus 650nm-300 red laser PWM laser lamp Wavelength: 650nm+-8nm Power: 300-M-w Adjustable focus (i.e. adjusting the size of the light spot) The power can be adjusted by adjusting the duty cycle through an external PWM signal! Working voltage: 12V Light class shape: circular (non perfectly circular)! Must read before purchasing: 1. The laser power module is relatively large, and eye contact is prohibited, otherwise it may cause permanent blindness, and the consequences are at your own risk! 2. Do not use in flammable and gaseous environments to avoid fire and explosion. 3. Children are prohibited from coming into contact with any laser products. 4. This laser comes with a power adapter that can be directly plugged into a socket to emit light. Please be careful not to expose it directly to your eyes! 5. Do not open the module to prevent damage. 7. PWM: 0-5V, Frequency<18K 8. The laser interface has three pins, with the red wire connected to a 12V+power supply, the yellow wire connected to a PWM+signal, the black wire connected to a power supply GND, and the white wire connected to a signal GND. The power supply and signal are grounded together! If the signal is not connected, simply connect 12V+and GND to emit light! No need to connect the signal again, the signal is only used to control the switch or adjust the power!
