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.
Newly redesigned 8x8 RGB LED matrix made using HD107s addressable LEDs. Easy to program: SK9822 and HD107s can be driven via 2-wire SPI bus, instead of needing specialized timing. Additional displays can be hooked up to make one large display matrix. Supports speeds up to 500,000 LED updates per second. Improved features include thinner board profile, grounded mounting holes, additional power pins, and flat solder pads for each external pin, to enable use of thicker wires.
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.
Available with or without JST connectors pre-soldered for easier hookup. If you choose the pre-soldered option, connectors are as follows:
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 one board connected. Additional "start frames" are actually recommended for this action, as they will prevent LEDs from lighting unexpectedly.
There are few LED boards using the newer SK9822 or HD107s model LED. I wanted to offer a better, easier to use product which uses newer technology for a fair price.
Unlike most 8x8 addressable boards which use the older WS2812 standard, these are made using newer HD107s LEDs. Advantages:
