Below is one real tested for 144leds HD107S and 144LEDs APA102. You can see obviously voltage drop for APA102 after 30leds, after 0.5m no signal and all leds turn red. for hd107s, only the end has a little voltage drop. also HD107S is brightness than apa102.
Pixel Protocol Overview: WS2815 This pixel protocol was designed by Newstar in China. WS2815 offers many of the benefits the WS28xx series is famous for. It uses 12V as its main power input for each chip, VDD, which is then dropped down to 5V inside [...]
Why we need high PWM for the pixel led strip? When we learn the IC chip specs, we always note there are two important rates, one is named refresh rate, another important parameter is PWM rate. These two above rates can be important in certain [...]
Pixel Protocol Overview: WS2814 This pixel protocol was designed by Newstar in China. WS2814 offers many of the benefits the WS28xx series is famous for, as well as being the first in the series to offer an RGBW design, making it one of the most [...]
Customer used HD107S 2020 addressable LEDs to make one big transparent led display, looks great! (Newstar is the orginal IC factory, they named NS107S, we bought their 107S IC to make LEDs, so named “HD107S”)HD107S 2020 transparent led display video
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 [...]
For different application, we discussed the Gamma curve of IC chips on digital pixel LED tapes. Considering on the IC chip is sheer volume in the variety, so we collating the various parameter values like Gamma curve of value and other parameters of these [...]
HD107s pixel RGB led used Newstar’s IC(NS107S), so we named “HD107S”, PWM refresh rate 27kHz, Oscillator Frequency 40MHz. Brief of HD107s LED 1, Althrough it is DC5V input, but it almost same voltage drop with 12V pixel led strip, 30leds/m HD107S 7m no voltage drop. 2, It is the fastest [...]
Why need to add Power Injection for the addressable LED Strip? When we offer the power to the led strips, you always can see the brightness is dimmer than the leds near to the power supply when the led strips are more than 3m length, [...]
HD107S 2020 LED for Music Bluetooth Audio
WS2182: 1-wire interface, fixed 800khz data rate, 400hz PWM rate, power draw up to 40mA/LED SK9822: 2-wire interface, variable up to 16Mhz data rate, 4.7khz PWM rate, power draw up to 40mA/LED HD107s: 2-wire interface, variable up to 40Mhz data rate, 27khz PWM rate, power draw [...]
