Review on 🔥 NEJE Laser Engraver Module 450nm PWM TTL CNC DIY Engraving Module - Replacement for NEJE Master 20W DIY Laser Engraver Machine - 5.5W Output Power by Kim Sanchez

Thought it was 20 watts but it's only 5.5 watts, it's bright and blue like a blue you never want to see. The glasses that came with it are junk. they do almost nothing. it's still super bright. not for kids. It has a long square beam. I'm still busy. The breakout board helps, but it comes with a bare circuit board. You just need to connect PWM and ground to your controller. Temperature green and 12V do not need to be connected. Just connect the module to a 12V adapter or use an adapter, PWM and ground. You press the right button twice, be careful it may go up to 100% when you first turn it on. depends on your controller. If you need to connect it, the website is rubbish, not a FB link, nothing. and their FB group is run by someone not even hired by them who told me these kits are rubbish. The website says 3.3V for PWM, but it requires 5V or 12V. It cuts fine. but the beam is wide. I'm a noob so I can go crazy. I had to put some 1kΩ resistors between ground and PWM. PWM is positive. Enjoy! I had to put some 1kΩ resistors between ground and PWM. PWM is positive. Enjoy! I had to put some 1kΩ resistors between ground and PWM. PWM is positive. Enjoy!
