## Description

A 16×8 LED matrix backpack kit featuring two ultra-bright 1.2" white 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. The 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. Key Features 16×8 White LED Matrix – Two ultra-bright 1.2" round 8×8 white matrices on one backpack HT16K33 Driver – Built-in clock and constant-current drivers for consistent brightness I2C Interface – Only 2 pins needed for full matrix control 16-Step Dimming – Adjustable brightness from very dim to full intensity Chainable – Up to 8 backpacks on one I2C bus (addresses 0x70–0x77) Ideal For Scrolling text displays and small signage Compact notification and status indicators Arduino and microcontroller display projects Multi-backpack chainable display setups Package Contents 1× 16×8 1.2" LED Backpack (fully assembled and tested) 2× Ultra-bright 8×8 round white LED matrices 1× 4-pin header Note: Some soldering is required to attach the matrices to the backpack.
