Hello everyone, in this video i made diy laser driver for my NUBM08 laser diode. The ready made driver which i had used in my previous video was damaged while testing so i decided to make my own laser driver with slightly current boosted as the previous board only supply 2 Amps and NUM08 can handle upto 3 amps max.
Here i used XL4015 stepdown CC/CV module for power and LR7843 to control the laser diode with the help of arduino (any pwm generator).
