Hi everyone, I'm very wet behind the ears here. Working on my first laser build now. Red diode powered by 5v input from old PSU. I purchased an AixiZ driver and come to realize that some were having issues with the driver.
Firstly, what is transistor-transistor logic and how do you use it? I also hear that on this driver, you must run a 1n4xxx diode between Vcc and TTL. Not sure why that is.
I was told that 5v input, the max output is slightly over 310ma. That seems like a lot for reds doesn't it? If I turn the pot on the driver down I could adjust it but wouldnt that excess power generate more heat and lower the life span? FYI, I am heatsinking the driver and output regardless. How would I go about handling this, or is it even an issue?
Thanks for reading
