Thanks for your lines.
I have some questions, I´ll appreciatte if you can answer them.
1) I understand that the two wires ( red and black, white connector) are for putting on/off the laser. I assume that you recommend to use a TTL switch in order to avoid 'rebounds' that can reduce the laser´s...
I finally purchased the 532 nm 200mW Laser with TEC. But I don´t know how to use it. It has no instructions, and I don´t know what to do (and what are them for) with the 4 inputs the board has.
Did you buy it? Could you please explain me what are the 4 inputs??
They seems to be the modulation...
