The classic round pixel design gives a retro dot-matrix aesthetic — ideal for scrolling text, small animations, or status displays in your projects.\n\nPowered by the HT16K33 driver chip, this backpack handles all the multiplexing over a simple I2C connection — no complex wiring or extra GPIO pins required. With 16-step brightness control and constant-current drivers, you get consistent, vibrant colour at any dimming level.\n\nKey Features\n\n\nHT16K33 Driver – Handles all LED multiplexing over I2C with a built-in oscillator\n\n16-Step Dimming – Adjustable brightness from barely visible to full intensity\n\nConstant-Current Drivers – Ensures uniform brightness across all 128 LEDs\n\nChainable – Three address-selection jumpers allow up to 8 backpacks on a single I2C bus (addresses 0x70–0x77)\n\nRound Pixel LEDs – Classic dot-matrix appearance\n\nCompact Design – Two 8×8 matrices on one board, controlled with just 2 I2C pins\n\n\nIdeal For\n\nScrolling text and message displays\nSmall animations and pixel art\nStatus indicators and dashboards\nWearable electronics and costumes\nInteractive art installations\n\n\nPackage Contents\n\n1× Fully assembled and tested 16×8 1.2\" LED backpack\n2× Ultra-bright round 8×8 yellow-green LED matrices\n1× 4-pin header\n\n\n\nNote: Soldering is required to attach the two matrices to the backpack. A microcontroller is needed to drive the display (not included).\n\n\nResources\n\n\nAdafruit LED Backpack Tutorial – Wiring, soldering, and code examples\n\nAdafruit LED Backpack Arduino Library – GitHub repository\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":8887,"title":"Default Title","sku":"AF-2036","price":33.06,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
