The WS2812 is very common in LED strips as it is an integrated controller and LED. It is driven by a single data line, but the timing requirements can be met by using most SPI controllers and the use of DMA. This driver has been validated on the nRF52 arch both with a single LED and a strip of 144. Signed-off-by: Brennan Ashton <bashton@brennanashton.com>
