The driver for this chain is the WS-2811or ucs1903 constant current LED driver. ucs1903 ic is a common, well-supported driver and example code is available for various microcontrollers. The 2-wire control scheme allows you to control the entire chain over only two GPIOs and because data cascades across the drivers.
