Three address-selection jumpers let you connect up to eight backpacks on a single I2C bus for larger display arrays.\n\nKey Features\n\n\nHT16K33 I2C Driver – Built-in multiplexing and constant-current drive for bright, consistent colour\n\n1/16-Step Dimming – Fine-grained brightness control via I2C commands\n\nI2C Interface – Only two data lines (SDA/SCL) needed, freeing up GPIO pins\n\nAddress Jumpers – Three jumpers allow up to 8 units on a single I2C bus\n\n1.2\" Yellow LED Matrix – 8×8 grid of ultra-bright yellow LEDs\n\nSimple Assembly – Solder the matrix onto the backpack in about 5 minutes\n\n\nAlso Consider\n\nSmall 1.2\" 8×8 LED Matrix w/I2C Backpack – Blue\nSmall 1.2\" 8×8 LED Matrix w/I2C Backpack – Green\nSmall 1.2\" 8×8 LED Matrix w/I2C Backpack – Pure Green\nSmall 1.2\" 8×8 LED Matrix w/I2C Backpack – Red\nSmall 1.2\" 8×8 LED Matrix w/I2C Backpack – White\n\n1.2\" 8×8 LED Matrix Backpack – Backpack driver board only (BYO matrix)\n\n\nPackage Contents\n\n1× Assembled and tested 1.2\" LED backpack (HT16K33)\n1× Ultra-bright 1.2\" 8×8 yellow LED matrix\n1× 4-pin header\n\n\n\nNote: Some soldering is required to attach the matrix to the backpack.\n\n\nResources\n\nAdafruit LED Backpack Tutorial\nAdafruit LED Backpack Arduino Library\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":6879,"title":"Default Title","sku":"AF-1050","price":22.31,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
