The driver is working as it should be whereas the diodes ar not. I tested them from the minimum current (0mA) to a max of 380mA and the output just isn't...

    Hi guys, new to the forum. So I bought a quite cheap 300mW 808nm diode off of ebay rated at 1.8V 350mA (max 400mA) and tried running it with a variable voltage/current module I got from Amazon. I tested the module beforehand for proper functionality and of course set up the current output using...
