This design has not yet been built and tested Cascade-able 5 Chip Neopixel board suitable for decorative lamps especially using the ESPEasy NeoFlame plugin.
Should work well with any Neopixel application that is suitable for groups of five LEDs. This board is for individual WS2812b LED chips. Not the ones pre-mounted on a heat sink pcb with resistor and capacitor already installed. Provisions are made for a large i.e 1000uF 10v Filter capacitor. Individual 0.1uF decoupling capacitors in 1206 SMD Size. Board uses a 1N4148 or similar SMD Diode to drop the supply voltage to the first WS2812 to about +4.7V. This will allow the board to be driven from 3.3V GPIO and still use a +5V Power Supply for the LEDs. Only the first chip requires the voltage drop, the cascaded chips will all be a +5V input logic leve.
