Digitally-controllable RGB LED pixel bars using WS2801 driver chips. Each 75mm plastic PVC bar contains 3× 5050 RGB LEDs and a controller chip, epoxy-flooded for waterproof outdoor use. Sold as a strand of 21 pixels — ideal for building large RGB 7-segment displays.

The pixels connect via a 4-conductor cable (+12V DC, ground, data, and clock). Data shifts from one pixel to the next, so strands can be cut or extended as needed. Each pixel is individually addressable with 24-bit colour (8-bit PWM per channel). Multiple strands can be daisy-chained using the JST SM 3-pin connectors.
