Ultra-bright 16×8 yellow-green round LED matrix board featuring an integrated STEMMA QT and Qwiic-compatible backpack for plug-and-play I²C connectivity

Description

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 16×8 LED Matrix Backpack we’ve doubled your project’s matrix capacity by making it super easy to get two separate 8×8 matrices onto one handy board! These ‘multiplexed’ matrices reduce the pin count needed compared to controlling individual LEDs directly.

This backpack includes:

• A fully tested and assembled 16×8 1.2″ LED Backpack
• 2x ultra-bright round 8×8 yellow-green matrices
• 4-pin header

A bit of soldering is required to attach the two matrices onto the backpack but only takes about 10 minutes. The kit uses a HT16K33 driver chip with a built-in clock, constant-current drivers for ultra-bright and consistent color, and 1/16 step display dimming via a simple I2C interface.

Each backpack has three address-selection jumpers allowing up to 8 matrices on a single I2C bus.

This item is great for making scrolling displays or small video displays. It is compatible with Adafruit libraries and tutorials to get you started quickly.

Note: The kit requires soldering and additional components like a microcontroller are not included.
