I had been hoping it would be possible to drive six SK9822 strips (identical static pattern, 30 LEDs each) in parallel with the prop shield, but it doesn't work. I'm using cool white DotStar strips from Adafruit, and, as I need them to be really dim, I'm using only one die per LED at very low brightness (29 mA per strip).
Three strips (90 LEDs total) is ok, four is too much, the pattern gets messed up.
I'm looking for an economical and breadboard-friendly solution (at this point this is just a feasibility study). Would the LED_CLK and LED_DAT outputs on the prop shield be able to drive all six inputs of a hex buffer in parallel? If so, which of the many out there (i.e., which family) would be best suited for this task? Or is my thinking wrong?
