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 90% power reduction when the LED is turned off.
8-LED stick using HD107s addressable LEDs. Easy to program: SK9822 and HD107s can be driven via 2-wire SPI bus, instead of needing specialized timing. Additional sticks can be hooked up, for example, to make a POV display. Supports speeds up to 500,000 LED updates per second.
These are compatible with most addressable LED libraries, just use the SK9822 or APA102 mode instead of WS2812. However, since they're compatible with a standard SPI bus, it's easy to write your own driver for a leaner, faster project overall.
Note that despite the datasheet, an "end frame" is not necessary, and serves only to push data to additional LEDs if you have more than 64 LEDs connected. Additional "start frames" are actually recommended for this action, as they will prevent LEDs from lighting unexpectedly, however if using fewer than 64 LEDs, the end frame can be omitted, and only the start frame is necessary.
There are almost no LED sticks made using the newer HD107s model addressable LED. I wanted to offer a better, easier to use product which uses newer technology for a fair price.
Unlike most addressable LED sticks which use the older WS2812 standard, these are made using newer HD107s LEDs. Advantages:
