Board for five individual Neopixel type APA 106 LEDs either 5mm or 8mm size. Two versions provided. The new one has positions for a large electrolytic filter capacitor and 1206 size decoupling capacitors (0.1 uF recommended) between LEDs. Not sure if all five decoupling caps are required, it may work with about three but positions are there.
Multiple Boards can be cascaded.
I did not provide a schematic as there is not too much to this and there was no suitable LED symbol available.
