On the adafruit page it says:
These LEDs are not shift registers. In fact, if you look closely, there's no input and output pin, only one data line. That's because each LED in this strand is pre-addressed from 0 to 100. Whenever it receives the NeoPixel data, it picks out the n'th color data (matching to its pre-address) and displays that. You cannot change the pre-address, its fixed permanently - or at least, we have no idea how to re-address it.
Yes, I read that bit. I'm trying to find out more.
They are obviously made in bulk, somewhere in china, since they are quite common, and cheap. Unfortunately, I've only found them in pre-built products, and none actually identify the chip model.
They obviously can be programmed (at least once) since you can buy arrays of at least 400. There is no way a factory is making 400 different chips, given the end price.
Are you looking for info on how to set the led color or something else?
I'm after a name or model for the chip/led itself. Potentially along with info on its extra functions.
