Lesson23- How to connect RGB LED strip using ESP32 by KC868-A4 A8 - admin - 10-25-2021
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

led strip chip model: WS2811 use DC12V
powe supply DC12V power supply not DC5V
CAN i use these model with A4 model ?

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.

Can I do the same using the analog inputs of KC868-A32?

Thank you!
What if I wanted to control (and dim) a regular LED strip that has a power supply like this one? Can I do that witch a32 too?
