Three address-selection jumpers allow up to eight backpacks on a single bus, so you can build larger or mixed displays with ease.\n\nKey Features\n\n\nI2C Interface – Only two data pins required (SDA + SCL)\n\nHT16K33 Driver – Built-in oscillator and constant-current LED drivers\n\nAdjustable Brightness – 1/16-step display dimming via software\n\nChainable – Three address jumpers allow up to 8 devices on one I2C bus\n\nCompact Size – 1.2\" (30 mm) square pixel matrix\n\nLED Colour – Blue\n\n\nIdeal For\n\nStatus indicators and simple animations\nScrolling text displays\nSensor data visualisation\nMulti-display arrays using I2C addressing\n\n\nPackage Contents\n\n1× Assembled and tested 1.2\" LED backpack (HT16K33)\n1× 1.2\" 8x8 square pixel blue LED matrix\n1× 4-pin header\n\n\n\nNote: Light soldering is required to attach the matrix to the backpack — approximately 5 minutes of work.\n\n\nResources\n\nAdafruit LED Backpack Tutorial\nAdafruit LED Backpack Arduino Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":13004,"title":"Default Title","sku":"AF-1853","price":26.33,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
