## Description

Features: . Wavelength: 532nm Output power: 95-120 Laser Shape: Dot Cooling methods: Fan cooling Modulation frequency: TTL 0-30K HZ Working Method: continuous work Color: Black Material: Aluminum Circuit control: constant control Reverse polarity protection: Yes, with automatic identification of positive and negative Operating voltage: DC = 12V Operating Current: I <500mA Warm up time: None Operating temperature: -10 ℃ ~ +40 ℃ Storage Temperature: -10 ° C to +40 ° C Structure: laser diode + lens + cooling Housing Laser Module Size: 74x30x30mm Circuit Board size: 71.5x35x20mm Notes: The 532nm Laser dot module is composed of 2 parts, Laser head (Laser diode+ housing +lens)and its driver circuit board. the laser head brings with fan cooling. The input voltage is 12V, an over-specified voltage will lead to damage of circuits and modules, if you have any technical problems, please contact us, thank you! This laser module can work for a long time! Please aviode direct eye exposure to the laser beam, please wear 532nm protection glasses when working on this laser module! This module cannot be focused, cannot adjust the size of the spot. TTL does not require connection and does not necessarily need to be used. Its main function is to connect to a signal generator and control the on and off of the laser by changing the magnitude of the current. Adjusting the current only brightens or dims the lightPackage: 1 x 12V 532nm Green Laser Dot Module Fan Cooling TTL 0-30KHZ-Long time working

Review: It will Work modulated TTL - I tested this puppy out, and I like it. For you folks that are wondering about controlling this PWM, you don’t need a schematic. Look at the board Silk screen next to the Red and Green connectors on the fan power side. This unit is designed to handle two lasers, a Red one plugs into the Red connector that is next to the Green one the Laser power cable is plugged into. The two empty Red and Green connects ( next to fan connect) are the TTL inputs. Looking down on top of those two empty sockets, with the notch side away from you, the right pin on both of these is Ground. The other pin, on both has a pull-up resistor to turn both lasers full on, when NO TTL signal is there. When your TTL signal is present, the left pin of that connector will be pulled low or high to the 5V TTL signal, and if it’s low, laser turns off, if it’s high the laser will be on. The TTL will in effect be turning laser off and on, according to your TTL control. If you just want to be able to turn Laser ON/OFF, you can just jumper the two pins and laser will be off. By the way the trimmer sets current level to both R-LD and G-LD outputs. Those extra unpopulated connector traces, I’m not positive of their use yet, but I’ll figure it out, and follow up. It’s very easy to control the brightness using TTL. Works for me. I’m not sure of the max current of this, but I tried the controller on a 1.6 Watt Blue Laser, and it worked perfect with TTL. By the way I hooked it in the same Green connector, the Green laser was using. I didn’t want to push it too hard, so I stayed with 12V supply, to see if it could handle the bigger Brother and it did. Try it out. Just jumper the two pins on that G-TTL connector and you’ll see, the Green laser go dark. Happy hacking.
Review: Had for a few months, rarely used, already dead. - purchased this in Mid August, hardly used it at all, and it's stopped working already. I didn't even start using it for at least a month after i got it, so it did last long at all. I would say if I used this regularly, it would have died in a week. Buyer beware.

## Questions & Answers

**Q: What are the wiring connections to modulate the beam?  Thanks!**
A: There is a seperate 2 pin connection for the TTL circuit on the circuit board.

**Q: Do you have a diagram of the board? Was expecting this in the package. No paperword what so ever.**
A: The picture shows the old driver board. In fact, the driver board has been upgraded and the position of the interface has been adjusted. We have a new connection diagram of the driver board. (The pictures on the current product link cannot be modified)

**Q: Will this work in my 3018 Pro?**
A: THis does not have the power to burn or cut with any speed. Did you have a different use for it?

**Q: There are three 2 pin connectors on the circuit board. which connector modulates the beam? polarity?  please answer the question this time.**
A: The first is for power (red/black), the second is for modulation (shorted=off, or 0-off +5 =on) and the third is for wiring a safety on/off switch.
