The Adafruit Mini 0.7" 8×8 LED Matrix with I2C Backpack makes it easy to add a bright blue 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.
