HD107S leds

Did anyone test this new type of leds with Hyperion? On paper there are perfect and because it's a new model there is a chance that Chinese didn't manage to make counterfeit clones of them (like APA102 where almost every APA102 sold on AliExpresses is in fact worse SK9822).

Compatible with APA102 protocol, speed of 40MHz and PWM = 26kHz looks really impressive. At least on the paper...
There's also other model HD108 but unfortunately not accessible for sale on Ali.
Rpi 3.3V fits HD108 logic levels and it's 16bits per color.

If anyone has trustworthy seller to recommend I could buy it on 11.11 and test it myself (my 2801 needs refresh after three years). This time I'll build a frame because my TV is a little too far from wall and colors of adjacent leds are mixed up.

"HD107S 2020-RGB /HD107S 3535-RGB /HD107S 5050-RGB on the market already.
The HD107S 5050-RGBW and HD107S led with 16 bits will on market In October2019"

something gone wrong....

Yeah, for sure it seems to be better option than other LEDS. Of course HD108 would be better for Rpi. I'm afraid about their reliability. My WS2801 works without any issues for years and I've read many reports about problems with other type of leds, mainly APA102 clones. I've just found direct seller from the manufacturer of HD107S and they have cheap 48led per meter, that's what I was looking for.

Why sk6812? One channel instead of two and very low bandwidth. I my case bandwidth is very important for high FPS grabber and smoothing at least 3xFPS. And account LED per meter. Must to calculate the frames size but I propably need more MHz than 800KHZ.

@pclin I saw some users on other forum waiting for them from January, no one can order them

And for the bandwidth:
For 55" Oled TV I need ~4m of LEDs.
Communication frame size: ~ LEDs * 4 bytes

For 30 led/meter:
4 * 30 * 4 * 8 +headers => ~3900 bits
30FPS * 3 smoothing = 90 => 351kHz at ideal condition

For 30 leds/meter 180 FPS => 700kHz

For 48 leds/meter 90FPS: 6200 * 90 => 560kHz
For 48 leds/meter 180FPS => 1.1MHz

For 60 leds/meter 90FPS: 7680 * 90 => 700kHz
For 60 leds/meter 180FPS => 1.4MHZ

But we are not living in the perfect environment. Some video frames could arrive late, there is overhead on internal communication and we need higher bandwidth than that minimum. I think that it's safe to assume 1.5 * that minimum. Almost all of one channels LEDs are unsuitable for most scenarios for me.

I think that I'll order that HD107..or maybe someone has a link to genuine, not counterfeit, not cloned Taiwanese APA102 as an alternative?

Received feedback from the manufacturer from China. HD108 can be ordered but the price is ~50$ per meter :eek:
