The seller seems to say it is a NiChia led, but can’t say wich reference, I didn’t open the cooler.

Earlier in the day I tried to burn an image using image2gcode, but it didn’t work.

My problem with the ttl level must be why I can’t get anything.

I tried to find out in marlin but couldn’t find an answer.

Testing the output gives 5V with M106 or M106 S255 but 0V between S0 and S254
