The Adafruit Mini 0.7" 8×8 LED Matrix with I2C Backpack makes it easy to add a bright yellow dot-matrix display to any project. The I2C backpack handles all the multiplexing, so you only need two data pins (SDA and SCL) plus power to control all 64 LEDs — no complex wiring or external driver chips required.
The backpack features a built-in display driver with constant-current output for ultra-bright, consistent colour at any brightness level. With 16-step dimming and address-selection jumpers, you can connect up to four 8×8 matrices on a single I2C bus for larger displays.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Address jumpers
- Address jumpers are small solder pads or links used to change a device’s bus address. They matter when you want to connect multiple identical displays to the same controller without their addresses conflicting.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
