This guide will show you how to add a microSD card to a Teensy 3.1 to play back animated GIFs on a 32×32 Pixel RGB LED Matrix Panel. The Teensy 3.1 runs an Arduino sketch that decodes the animated GIF and refreshes the display at a high frame rate with good color depth. The SmartMatrix Shield makes it easy to connect everything together.
We will explain the basic soldering and wiring to connect the microSD card reader to the SmartMatrix Shield, how to compile the Arduino sketch that decodes the GIF animations, and go over options for creating your own GIFs.
