Adafruit Small 1.2 8x8 LED Matrix w/I2C Backpack - Pure Green

The Adafruit Small 1.2" 8×8 LED Matrix w/I2C Backpack in pure green combines a bright 8×8 LED matrix with a dedicated HT16K33 driver backpack, letting you add a compact display to any microcontroller project with just two I2C data lines.

Instead of wiring 16 pins to multiplex 64 LEDs, the backpack handles all the multiplexing, constant-current drive, and 1/16-step dimming over I2C. Three address-selection jumpers let you connect up to eight backpacks on a single I2C bus for larger display arrays.

Key Features

• HT16K33 I2C Driver – Built-in multiplexing and constant-current drive for bright, consistent colour
• 1/16-Step Dimming – Fine-grained brightness control via I2C commands
• I2C Interface – Only two data lines (SDA/SCL) needed, freeing up GPIO pins
• Address Jumpers – Three jumpers allow up to 8 units on a single I2C bus
• 1.2" Pure Green LED Matrix – 8×8 grid of ultra-bright pure green LEDs
• Simple Assembly – Solder the matrix onto the backpack in about 5 minutes
