HD107S LEDs for MRCC – MIDI Router Control Center

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 outputs, including 5 PIN DINs, 3.5MM MIDI jacks in both flavors, 4 USB host ports (with 4 virtual ports each), and a USB client (PC or tablet) connection with 12 MIDI ports. With clock source, [...]

HD107S/SK9822/WS2812B

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 up to 30mA/LED SK9822 and HD107s also have a 32-level brightness value, which gives improved control at lower brightness. HD107s supports a sleep mode providing up to 99% power reduction when the LED is turned off. What [...]

Different Pixel LEDs-Comparison

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 4feet One wire to control LED (asynchronous) Refresh rate of 400Hz, restricted data rate of 800Hz Not suitable for POV (Persistence of Vision) applications (too slow in refreshing) Interrupt compatibilityAPA102, HD107S4wires 6feet 2 wire SPI pin (CLK & DAT) (synchronous) No strict [...]

how to choose the best digital LEDs?

  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 the correct chip inside of the LED strip so that you can also control it. Using this chip a addressable LED strip can control each individual digital LED on the strip and give them all different [...]

The voltage drop of APA102 and HD107S

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. 

HD107S 144LEDs compare APA102 144LEDs

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.Let’s show the APA102 LED Strip testing, 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 160, and I connected a strip of 144.  The oscilloscope traces are the [...]

HD107S 30pixels led strip project in the feast of St Josep

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 quality, better performance than ws2813, so we suggest customer use HD107S to replace ws2813 led strip. this strip is 30leds/m, 6m per roll, black PCB with silicone waterproof.Contact us, hd-pixels@hotmail.com  

HD107S 2020 LED Display

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
