This is a UART serial to addressable LED driver board. It supports these LEDs (and compatibles):
It can be used with just about any microcontroller's serial (UART) port(s), Raspberry Pi, USB serial adapters, and even software serial implementations. The outputs are level-shifted to 5v with 100 ohm impedance matching resistors for twisted pair like found in CAT 5/CAT 6. The protocol allows for up to 8 driver boards to run from the same serial line, with cuttable jumpers to set the address. Pixel data is buffered, and displayed simultaneously across all channels, and includes CRC error checking to prevent glitches.
Each channel can have its own color ordering, and can support a mix of RGB and RGBW across channels or LED types, and any mix of length, up to 800 RGB pixels or 600 RGBW pixels per channel for the WS2812 / NeoPixel types, and 600 LEDs for the APA102 / DotStar types. Thats up to 6,400 pixels per board, or 51,200 with eight!
Since data is buffered on this board and the protocol doesn't have any timing requirements, you can calculate pixel data on the fly and there's no need to buffer anything on your micro, freeing up memory.
For APA102 / SK9822 / DotStar, at least one channel is dedicated to clock output. This can be shared to multiple LEDs clock inputs, so you can drive up to 7 channels of APA102.
You can mix and match APA102 with WS2812 on the same board by specifying each channels type.
The input serial protocol runs at 2Mbps. This allows up to 66k pixels/sec to be drawn per serial line, about twice the speed of typical WS2812.
Power and GND connections are also available per channel, and works great for lower powered applications (up to 3 A).
In this kit you get the driver board (pictured), 5mm screw terminals, and 0.1" pin headers. It's sold as a kit, and some easy soldering is involved to attach the optional screw terminals and headers.
Originally designed to expand output options for the Pixelblaze, this driver board can be driven by just about any micro.
This solves many issues that are tough to accomplish with existing hardware/libraries:
