{"title":"75mm Bars - 12V Digital RGB LED Pixels (Strand of 21) [WS2801]","handle":"75mm-bars-12v-digital-rgb-led-pixels-strand-of-21-ws2801","url":"/products/75mm-bars-12v-digital-rgb-led-pixels-strand-of-21-ws2801","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.\n\nThe 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.\n\nKey Features\n\n\n21 Pixels Per Strand – 75mm bar format with 3× 5050 RGB LEDs each\n\nWS2801 Controller – 24-bit colour, individually addressable\n\nWaterproof – Epoxy-flooded PVC enclosure\n\n12V DC – Constant-current driven for even colour throughout\n\nChainable – JST SM connectors for extending strands\n\nMounting Options – Flanges with 4mm holes and adhesive foam tape\n\n120° Beam Width – ~4000mcd total brightness per pixel\n\n\nSpecifications\n\n\nLEDs Per Pixel – 3× 5050 RGB (controlled as one unit)\n\nPixel Size – 75mm bar\n\nVoltage – 12V DC\n\nInterface – 2-wire (data + clock), any two digital pins\n\nConnectors – JST SM 3-pin (data), separate power wires\n\n\n\nTip: 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.\n\n\nResources\n\nArduino Library (GitHub)\nLED Pixels Tutorial (Adafruit Learn)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8542,"title":"Default Title","sku":"AF-1548","price":97.45,"on_sale":false,"in_stock":true,"available_quantity":7,"option1":"Default Title"}]}
