## Description

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. Key Features 21 Pixels Per Strand – 75mm bar format with 3× 5050 RGB LEDs each WS2801 Controller – 24-bit colour, individually addressable Waterproof – Epoxy-flooded PVC enclosure 12V DC – Constant-current driven for even colour throughout Chainable – JST SM connectors for extending strands Mounting Options – Flanges with 4mm holes and adhesive foam tape 120° Beam Width – ~4000mcd total brightness per pixel Specifications LEDs Per Pixel – 3× 5050 RGB (controlled as one unit) Pixel Size – 75mm bar Voltage – 12V DC Interface – 2-wire (data + clock), any two digital pins Connectors – JST SM 3-pin (data), separate power wires Tip: A 12V 5A power supply can drive 3 or more strands depending on current usage. Use a 2.1mm terminal block adapter to connect the separate power wires. Resources Arduino Library (GitHub) LED Pixels Tutorial (Adafruit Learn)
