@TedW. I received my boards last Thursday, didn’t open the envelope until Saturday. Thought pretty much the same thing as you, doubt that I will successfully get the LED’s soldered on the board. I might attempt it at some point but since one LED costs more than three of the boards, maybe not. I bought six boards because buying only three seemed like I was being “cheap.”
I also bought six of the single LED boards, I already have LEDs for them.
