UPDATED GUIDE: Matrix and 7-Segment LED Backpack with the Raspberry Pi #AdafruitLearningSystem #Adafruit @Adafruit
The Matrix and 7-Segment LED Backpack with the Raspberry Pi has been updated to utilize the super user friendly adafruit-circuitpython-ht16k33 library. This guide provides three examples of working with an 8×8 matrix and a 7-segment display over an I2C interface. It has never been easier to use a Raspberry Pi to drive a display. The examples provided will work on all versions of Raspberry Pi that have a GPIO header (26 or 40 pin).
The LED backpack displays are wonderfully easy to connect to the Pi. Both the 8×8 pixel and 4-character 7-segment displays are connected the same way, with two digital pins for I2C (SDA and SCL) and two power pins (VCC and GND).

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
