## Description

The 16×8 1.2" LED Matrix + Backpack combines two ultra-bright square pure green 8×8 LED matrices on a single, compact driver board. The square pixel design creates a seamless, uniform look — perfect for scrolling text, small animations, or status displays in your projects. Powered 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. Key Features HT16K33 Driver – Handles all LED multiplexing over I2C with a built-in oscillator 16-Step Dimming – Adjustable brightness from barely visible to full intensity Constant-Current Drivers – Ensures uniform brightness across all 128 LEDs Chainable – Three address-selection jumpers allow up to 8 backpacks on a single I2C bus (addresses 0x70–0x77) Square Pixel LEDs – Seamless, uniform appearance with no gaps between pixels Compact Design – Two 8×8 matrices on one board, controlled with just 2 I2C pins Ideal For Scrolling text and message displays Small animations and pixel art Status indicators and dashboards Wearable electronics and costumes Interactive art installations Package Contents 1× Fully assembled and tested 16×8 1.2" LED backpack 2× Ultra-bright square 8×8 pure green LED matrices 1× 6-pin header Note: Soldering is required to attach the two matrices to the backpack.
