Customer used NS107S 2020 addressable LEDs to make one big transparent led display, looks great! (Newstar is the orginal IC factory, they named NS107S, Hida bought our 107S IC to make LEDs, so named “HD107S”)NS107S 2020 transparent led display video
Do you know the difference of APA102, APA107,NS107s and SK9822? APA102: 20+ kHz PWM. APA107: 9 kHz PWM. NS107s: 27kHz PWM (the upgrade of APA107). SK9822: 4.7 kHz PWM. Newstar study the APA107/NS107S based on APA102 technology, so APA107 and NS107S is same protocol with APA102, same pcb/same controller, can replace APA102 directly. And APA107 is better than SK9822, but almost same cost. NS107S is much better APA102, but the cost is cheaper. NS107s pixel led chip with PWM refresh Rate 27KHZ and transmission rate 40MHZ Apa107 [...]
HD107s pixel RGB led used Newstar’s IC, so we named “HD107S”, Newstar’s model number is Ns107s. the HD107s LED can be used to make led strip ,led tube, pixel led dot , led bar,ect . Brief of HD107s LED The fastest digital pixel led HD107s -it is a update of apa102 led, which is Absolutely a best perfect pixel led to replace APA102/APA102C/APA107/SK9822, bec it is much more stable and faster and energy saving . and HD107s LED has the fastest Transmission speed and refresh Rate among [...]
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 [...]
