APA102 addressable led strip
Maybe you will consider that there are ws2811 and ws2812b why we still need apa104 and apa102 led strip,i am not familiar about them,do they really as good as you say? you might habitually refuse to know about them,convinced that hype advertising,frankly speaking if you think it like that you might kill great products and miss this significant business chance.it is better to see for oneself rather than to hear for many times.General Characteristics :built in ic,individual control,DC5V input voltage,20mA current, gray scale is 256,but what you need to know is the difference,that is the Point:one data cable,one independent clock cable for built in ic,refresh speed is faster,the signal is much more stable and travel much faster than other built in ic leds.
