The Ebay item is:

The wiring was just a ‘daisy chain, D to Din, Dout to Din etc, plus the 5V & 0V connect to + & – on the Crumble.
I could control the first LED but none of the others – sorry I can’t screen shot the code but it was just “Set sparkle 0 to red, wait 1 second, set sparkle 1 to red, wait 1 second”, all inside a ‘Do Forever Loop’
