{"title":"16x8 1.2 LED Matrix + Backpack-Ultra Bright Round Orange LEDs","handle":"16x8-1-2-led-matrix-backpack-ultra-bright-round-orange-leds","url":"/products/16x8-1-2-led-matrix-backpack-ultra-bright-round-orange-leds","description":"A 16×8 LED matrix backpack kit featuring two ultra-bright 1.2\" orange 8×8 round LED matrices on a single I2C-controlled driver board. The HT16K33 chip handles all the multiplexing, so you only need two I2C pins (SDA and SCL) to control 128 LEDs — no complex wiring required.\n\nThe backpack features constant-current drivers for consistent brightness, 1/16-step dimming control, and three address-selection jumpers allowing up to 8 backpacks on a single I2C bus. A small amount of soldering is required to attach the two matrices to the backpack board.\n\nKey Features\n\n\n16×8 Orange LED Matrix – Two ultra-bright 1.2\" round 8×8 orange matrices on one backpack\n\nHT16K33 Driver – Built-in clock and constant-current drivers for consistent brightness\n\nI2C Interface – Only 2 pins needed for full matrix control\n\n16-Step Dimming – Adjustable brightness from very dim to full intensity\n\nChainable – Up to 8 backpacks on one I2C bus (addresses 0x70–0x77)\n\n\nIdeal For\n\nScrolling text displays and small signage\nCompact notification and status indicators\nArduino and microcontroller display projects\nMulti-backpack chainable display setups\n\n\nPackage Contents\n\n1× 16×8 1.2\" LED Backpack (fully assembled and tested)\n2× Ultra-bright 8×8 round orange LED matrices\n1× 4-pin header\n\n\n\nNote: Some soldering is required to attach the matrices to the backpack.
