The backpack handles all LED multiplexing and driving via I2C, so you only need two data pins to control a full 4-digit display.\n\nThe HT16K33 driver chip provides constant-current output for consistent brightness, 1/16-step dimming control, and a built-in oscillator — no external components needed. Address-selection jumpers allow up to eight 7-segment displays on a single I2C bus.\n\nKey Features\n\n\nHT16K33 I2C Driver – Built-in multiplexing, constant-current drive, and 1/16-step dimming\n\nSimple I2C Interface – Only two pins required, with address jumpers for up to 8 displays on one bus\n\nUltra-Bright Red LEDs – 0.56\" digit height, visible from a distance\n\nArduino and CircuitPython Libraries – Well-documented libraries for quick setup\n\nCompact Design – Backpack mounts directly behind the display\n\n\nAlso Available\n\nBlue\nGreen\nWhite\nYellow\n\n\nAlso available in a larger 1.2\" size, or as a pre-assembled version.\n\nPackage Contents\n\n1× Adafruit I2C LED backpack (assembled and tested)\n1× 0.56\" 4-digit 7-segment red display\n1× 4-pin header\n\n\n\nNote: A small amount of soldering is required to attach the display to the backpack board.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14150,"title":"Default Title","sku":"AF-878","price":19.41,"on_sale":false,"in_stock":true,"available_quantity":26,"option1":"Default Title"}]}
