Control all 128 LEDs with just two I2C wires — the driver chip handles multiplexing, constant-current drive, and 1/16-step dimming automatically.\n\nThe bicolour LEDs display three colours: red, green, and yellow-orange (both LEDs on simultaneously). Address-selection jumpers let you connect up to eight bicolour matrices on a single I2C bus for larger displays.\n\nKey Features\n\n\n1.2\" 8×8 Bicolour LED Matrix – Red, green, and yellow-orange (3 colours from 2 LEDs)\n\nHT16K33 I2C Driver – Built-in multiplexing and constant-current drive for consistent brightness\n\n1/16-Step Dimming – Adjustable display brightness over I2C\n\nI2C Interface – Only 2 wires needed to control all 128 LEDs\n\nAddress Jumpers – Connect up to 8 bicolour matrices on one I2C bus\n\nSimple Assembly – Solder the matrix onto the backpack in about 5 minutes\n\n\nIdeal For\n\nSmall pixel displays and status indicators\nSimple animations and scrolling text\nMulti-colour visual feedback in projects\nTiled display walls using multiple matrices\n\n\nPackage Contents\n\n1× Assembled and tested LED backpack (HT16K33)\n1× 1.2\" 8×8 bicolour (red/green) LED matrix\n1× 4-pin header\n\n\n\nNote: Some light soldering is required to attach the LED matrix to the backpack.\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":14270,"title":"Default Title","sku":"AF-902","price":33.17,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
