But it can also be used for other diy machine which need to change ttl modulation.
Diy laser driver ttl.
Hope this helps you set you system up and get it working.
For the driving of the laser diodes ld special drivers circuits are used.
Useful software for lasers and laser engraving cutting machines.

In other words if you have 3 5v output with 50 duty ratio the laser will work with 50 power and the same will be if you have 24v output pin and 50 duty ratio.

The second type is more easy to design and use and different circuits for their implementation exist.
They can work in two ways.
For example ttl will activate the laser at any voltage in this range at any duty ratio without changing the laser power.
