Adafruit 16x8 1.2" LED Matrix+Backpack UltraBright Round YellowGreen LEDs

What's better than a single LED? Lots of LEDs! And what's better than lots of LEDs? Two times as many LEDs! With the 16x8 LED Matrix Backpack, your project's matrix capacity doubles, effortlessly integrating two 8x8 matrices into one compact board.

Matrices like these are 'multiplexed'—to manage 64 LEDs, 16 pins are needed, and 128 LEDs demand 24 pins. This innovative product saves you from complex wiring and space-hogging setups. The MAX7219 driver chip controls the matrix but requires significant wiring; our solution eliminates this hassle.

The 16x8 LED matrix backpack excels in creating scrolling or small video displays, effortlessly transitioning text across matrices, simulating a miniature car dealership sign. Powered simply by a Trinket, the entire setup remains compact and neat.

Utilizing the HT16K33 driver chip, this backpack simplifies operations, featuring constant-current drivers for ultra-bright, consistent colors and 1/16 step display dimming, all via a straightforward I2C interface. Each backpack includes three address-selection jumpers, connecting up to 8 matrices on a single I2C bus.

Kit includes: a fully assembled 16x8 1.2" LED Backpack, two ultra-bright round 8x8 yellow-green matrices, and a 4-pin header. Minimal soldering is required to attach matrices, taking approximately 10 minutes—aided by a detailed Adafruit tutorial and a user-friendly library for rapid setup.

This solution allows you to explore matrix displays without the intimidation of complexity. Transform your projects with vibrant displays, comfortably and confidently.
