Pixel Protocol Overview: HD107SHD107S is very similar to the APA range and boasts everything APA102 brings, with a higher PWM rate and brighter LEDs. The control circuit and LEDs are integrated in a 5050 SMD package, which provides a small physical footprint for each pixel.
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 [...]
Pixel Protocol Overview: WS2818 This pixel protocol was designed by Newstar in China. WS2818 offers many of the benefits the WS28xx series is famous for, as well as being the first in the series to support an output voltage of up to 24V, making it [...]
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 [...]
Pixel Protocol Overview: APA107
This pixel protocol was designed by Newstar LED in China, who use the 107 chip by Newstar. Very similar to the APA range, APA107 boasts everything APA102 brings, with 9Khz PWM rate and brighter LEDs. The control circuit and LEDs are integrated in [...]
HD107S 30pixels led strip project
it’s for the fire show( Malta freedom day ) at the end of march friday in the feast of St Joseph.
This project start from our client shared a video，After check some informations we recommend the
HD107S led strip, because it is the top [...]
Pixel Protocol Overview: WS2813 This pixel protocol was designed by Newstar in China. WS2813 offers many of the benefits the WS28xx series is famous for, as well as being the first in the series to offer both a redundant data line and a much higher [...]
LEDs come in lots of different shapes and sizes. For Analog digital LEDs, where the whole strip becomes a single color, choice is mostly about the size, wattage and density of the strip. For digital LEDs it’s also important to make sure you get [...]
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 [...]
