I heard Newstar produce one very nice LEDs, SPI signal, fastest in the world, can replace APA102 LEDs directly, with much lower price, named NS107S series, now have 5050/3535/2020 size, RGBW will be present as soon…
PWM refresh rate 28kHz, Transfer speed can be 40MHz, static power consumption is zero…many interesting chracters
Does any one test it? can you show the test report?
I found this picture from internet.
