FB04-500 500mW 405nm Blue Violet Laser Module 2*2.54-2P TTL/PWM Modulation for EleksMaker Engraver

Whats the diference between FB03 Series and FB04 Series Laser Module When or why do i need to have a FB04 Series Laser Module It depends on what the interface for laser module on your controller board is like The controller board of EleksMaker Series Engraver is designed with a 3 Pin 12V GND PWM interface for laser module so you need to buy a FB03 series module If the controller board of some other no name engravers is designed with 2 2 Pin 1 for DC voltage 1 for PWM TTL modulation interfaces then you need to buy a FB04 series module to fit it Specification General Specification Model FB04 500 Heatsink Material Aircraft Aluminum Luminous ColorBlue Violet Section Size 33mm x 33mm Mounting Hole M5 central M3 around Cooling ModeHeat Sink Groove Cooling Fan Adapter PlugUS Plug Adapter Input VoltageAC 100 240VAdapter Output VoltageDC 12V 2 5A Can EngraveMDF Balsa Paper Wood Fabric Plastic Leather Plywood Foam Paper Anodized Aluminum Can Not EngraveMetal Glass Stone Ceramics Stainless Steel Reflective Material Transparent Material Technical Parameters Laser Power500mW 0 5W Wavelength405nm Beam ShapeDot Focusable Working VoltageDC 12V TTL PWM ModulationYES Power Input Interface 2 54 2P TTL Interface 2 54 2P Drive ModeExternal ACC Constant Current Drive Life Time10 000 hoursFeatures 1 The voltage for power port VCC GND 2 Pins Port is DC 12V the voltage for PWM port PWM GND 2 Pins Port is DC 5V 2 405nm 500mW focusable blu
