Customer used HD108 2020 addressable LEDs to make one big transparent led display, looks great! (Newstar is the orginal IC factory, they named NS108, we bought their 108 IC to make LEDs, so named “HD108”)HD108 2020 transparent led display video
Do you know the difference of HD107s, HD108, APA107, APA102 and SK9822? APA102: 20+ kHz PWM, 8bit 256 grayscale APA107: 9 kHz PWM, 8bit 256 grayscale HD107s: 27kHz PWM (the upgrade of APA107), , 8bit 256 grayscale HD108: 27kHz PWM, 16bit 65536 high grayscale SK9822: 4.7 kHz PWM, 8bit 256 grayscale Newstar study the APA107/HD107S/HD108 based on APA102 technology, so APA107, HD107S and HD108 are same protocol with APA102, same pcb/same controller, can replace APA102 directly. And APA107 is better than SK9822, but almost same cost. HD107S is much better APA102, [...]
HD108 pixel RGB led used Newstar’s 108 IC, so we named “HD108”, Newstar’s model number is Ns108. HD108 LEDs it is each output channel can output 16-bit (65536 Level) High gray-scale adjustable linear current LED chip Brief of HD108 LED HD108 is the fastest 16bit 65536 digital pixel led HD108 -it is a update of HD107S led, PWM is same, but color is more complete. Now in the market only has 3kinds pixel leds with 16-bit (65536 Level) High grayscale, HD108, APA102-65536 and SK9826 HD108 led has PWM [...]
According to Paul Stoffregen’s Articles on December 6, 2017December 7, 2017, we know the APA102 LEDs strips have the problem at 24 MHz, usually after 150 to 250 LEDs. But why? Here’s his attempt to investigate:One tempting explanation is signal quality problems due to horribly messy unterminated wiring carrying high speed signals, as in this photo! But it turned out to be a more fundamental timing problem.In this test, a Teensy 3.2 runs the FastLED “Cylon” example with this line:LEDS.addLeds<APA102,11,13,RGB,DATA_RATE_MHZ(24)>(leds,NUM_LEDS);NUM_LEDs was set to [...]
