Hi all. I'm new here and this has me stumped. This was part of a circuit that made a tiny pico flicker. It itself didn't light up though. It clearly looks to be a 2 color LED with a common cathode. But it didn't light up at all. And how would that even make the pico flicker anyway? The pico was wired to the negative and the positive was wired to the common cathode. Looks to have a processing chip or two as the flicker. So was this a 2 color flicker LED? Does anyone know where to find these? Unfortunately I can't test it anymore as something got fried somewhere. Ran off of 3v. But, again, only the pico lit.
