Lesson23- How to connect RGB LED strip using ESP32 by KC868-A4 A8
#1

LED Strip chip model: WS2812B

every LED have R,G,B colors:
every LED cost R: 20mA+G: 20mA+B: 20mA=60mA

if you using 1 meter = 30 LEDs 
total cost:60mA*30=1800mA=1.8A  so chose DC5V 2000mA power supply

if you using 10 meter, so will use 300 LEDS
total cost:60mA*30*10=18000mA=18A  so chose > DC5V 18A power supply

you can confirm with your LED strip supplier, whether the LED strip DATA pin is 5v level, if it is, ok no problem with A4 module.
