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 [...]
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.

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, [...]
When you scan our web that you can find our 90% DMX512 led tapes are the UCS512 version, especially for the DMX512 RGBW LED tapes are the UCS512C4 series. But UCS512C4 version have an obviously shortcoming that is low bit which is only 8-bit gray scale [...]
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 [...]
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 [...]
Reinventing the Classic MIDI Router
A fresh approach: featuring one button routing for each physical input and output, RGB HD107S LEDs, and OLED graphical display, everything can be easily setup without a PC. It will be the centerpiece of your studio!
Massive MIDI I/O: 11 inputs and 17 [...]
Comparison LED Strips: WS2812B, SK6812, APA102, HD107S
All LEDs are SMD5050 to compare (they also have 3535/2020/1515 size). There are RGB and RGBW variants for some of them (W of RGBW is used for an additional white LED 3000k/4000k/6000k CCT).
These LEDs fall into two categories:WS2812B, SK6812:3wires [...]
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 [...]
