Hello,
I'm working with 5 mm square, four-prong HF5 R5590 10 lumen LEDs.
I don't understand the four-pin layout. Which are the cathodes and which are the anodes? On the illustration, there is one tiny bit of corner missing. I wish it were that plain in the LEDs they sent me. But I can just barely see it.
When I orient the diode as best as I can figure, and push down about 1/8 inch where it stops, it springs back up. It does not engage the connections under the top of my board.
The pins each have a 'bump" about halfway up, making them look like miniature swords and that stops the pins from sliding into the holes on my breadboard. I "Pressed" one LED into the board with about 50 pounds of pressure ands it snapped in. I had to pry it back out. I didn't look at the breadboard to find any damage that might have done.
If I had a 20-power binocular microscope, I could have closely examined that LED for cracks, etc.
Do I need to solder short pieces of 20 gauge copper wire to the prongs to make them work in my breadboard?
