Where can you buy the led light shown on ROCKET LAUNCH PAD by MauricioDUARTE
In that illustration though it looks like the LEDs only have 2 wires. RGB LEDs will have 3 wires (neopixels: +/-/data) or 4 wires if common anode or cathode and the other wires brought out individually.
But no idea the correct answer. Might be best to ask the designer directly?
