What is it?

This module allows you to use Third party laser kits such as " Focusable High Power 2.5W 450nm Blue Laser Module TTL " with the Genmitsu 3018 GRBL Control board.

Note : Laser as in picture not included in this listing.

Why did you make it?

I needed to interface such type of laser to the 3018 GRBL control board. The problem is that these type of lasers need an active low pwm to power on. Thus an inverting module is needed between the control board and the laser regulator board.

What makes it special?

This board will control such a laser easily. By using triple Darlington array, the laser is switched on only when engraving.

Features

• 0.2V - 5v Input - Opto-Isolated Input PWM making it fully isolated from the control Board - TTL signal input 0~5V input.(0V OFF/5V ON).

• uses JST 2 pin connectors for power, input and output connections

• On Board 5v Regulator and Filtering as needed on power rails

• uses Discrete BJT Transistors

• Just 60 x 40 Sits on top of the laser control board.

What is Included : Assembled and tested laser inverting board.
