The TinyShield Matrix LED Boards is a 6 x 9 grid of LEDs (54 total LEDs) that are individually addressable, which lets you scroll text, draw images and all sorts of other things. This TinyShield is compatible with the popular Arduino LoL Shield Library (Lots of LEDs Shield) created by Jimmie Rodgers.

The LEDs are arranged using Charlieplexing, which is a technique to allow for control of multiple LEDs using fewer I/O signals. Available with Red, Green and Amber LED color options.
