Feature:
1. Made of high quality hard aluminum and brass material, the surface is by anodized and sandblasting , not easy rust, very durable.
2. With heat dissipation fan, make it with longer service life.
3. Output optical power is stable, suitable for industrial equipment usage. 
4. 3 Pins plug, TTL/PWM drive mode, suitable for laser engraving machine equipment usage.
This module can be compatible with TTL or PWM modulation, (But it can just select either function at a time.) while TTL can control the switch on/off and PWM can control the adjustment of laser power.
5. Can Engrave: MDF/Balsa/Paper/Wood/Fabric/Plastic/Leather/Plywood/Foam Paper
6. Can Not Engrave: Anodized Aluminum/Ceramics/Stone/Stainless steel/Metal/Glass/PCB/Reflective Material/Transparent Material

Note:
1. This laser module has high output power, please wear goggles when testing or using.
2. Do not touch the laser light directly in cases that hurt the body and skin.
3. Keep children and pets away from the laser module when it working.
