APA107-5050 RGB LEDs is the newest addressable LED chip on 2018 years, PWM refresh rate can be 9khz, Oscillator frequency can be 30Mhz, can replace APA102 LEDs directly, and APA102/APA107 use same PCB to produce LED strip. But APA102-5050 RGB LEDs is 20Khz, so APA107 LEDs is one economic addressable LEDs with much lower price than APA102 LEDs, but much much better than SK9822 LEDs.
APA107 made in China manufacturer, Newstar is the owner for APA107 IC. Due to the perfect performance of APA107, so many China factory buy APA107 IC from Newstar and produce the addressable LEDs by themself, somebody sell the LEDs as new SK9822 or new APA102, also named a new type with LC8822....
However APA107 LEDs as a economic addressable LEDs to replace APA102 is not enough, as the PWM refresh rate is only 9Khz, meanwhile Taiwan APA company ask us stop use "APA" to named the LEDs, so we swear that we will make a much better LEDs than APA102, no matter APA102-5050 or APA102-2020.
On November 2018, We Newstar developed the LEDs, named "NS107S", not use "APA". The testing lasted as long as six months, finally we got a perfect LEDs.
NS107S-5050 RGB LEDs with higher PWM refresh 28Khz, Maximum transfer speed can be 40Mhz, and static power consumption is 0ma, zero, zero....and brightness is much higher than APA102-5050, lower voltage drop...everything is perfect, absolutely it is the best and fastest LEDs in the world.
As Newstar also sell "NS107S" IC to other company, so they produce the LEDs by themself and named different model, BUT never be "APA107S", NEVER!
BTY, Newstar will present NS107S-3535, NS107S-2020, NS107S-RGBW....as soon.
