LM2596
Drok tech,
I bot 2 5-paks of the LM2596 buck VR. I used 4 w/blu led that worked perfectly. Now, I am trying to get a few others going, the 2nd 5-pak has red leds. Testing 2 new w/blu & 3 w/red: 12v in =12v out all day long. Not variable. What am i missing?
I am a retired EE and have alot of fun with Drok products.
Thx Fanden
