16x8 1.2 LED Matrix + Backpack - Ultra Bright Square Green LEDs
26 units available with a short lead time.
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)
