Hello everyone,
I just bought some more or less noname 250mW 650nm laser diodes (de.aliexpress.com/item/4000826011161.html). I removed the heatsink and at the back of the driver I can see the "SANWU" tag. The circuit-board in the shop-images does not match the one I can see with the heatsink removed.
Ultimately I am looking for the proper way to power and switch the diode with an arduino board. The laser then will fire atclover, identified by a camera and KI sitting on a hexapod robot, moving around in my lawn.
I am not realy sure, which components I need. At first I though, that I need a MOSFET to switch and regulate the current to the laser, because I did not trust the internal regulation in the bought diodes. But since I found quite some articles about Sanwu and their lasers here, maybe someone can tell me if I can rely on the internal regulation or not?
Either way, I then need to have a small ciruit to switch the laser on and off. At best with the possibilty to regulate the current somehow (two steps high/low would be sufficient), to first try it on a lower power level. The external power-source will be a USB-Charger-pack with 5V DC.
Although I have electrical background, I would like a simple circuit, as I do not have much experience or equipment for circuit boards and soldering and need to buy them explicitly for this project.
Looking forward to your help!
Cheers
SEB
