TinyShield Matrix LEDs (HCTICI0033 - 35)

Post by andrew » Wed Oct 07, 2015 1:06 pm



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 colour options.

See our Tiny Circuits Range Here.


54 Top Facing LEDs in a 6×9 Matrix
Ultra compact size and weight (smaller than a US Quarter!)
Square Version: 20mm x 20mm (.787 inches x .787 inches)
Max Height (from lower bottom TinyShield Connector to upper top of LEDs): 4.6mm (.181 inches)
Weight: TBD grams (TBD ounces)
Arduino pins 2, 3, 4, 5, 6, 7, 8, and 9 are used by this shield

The TinyShield Matrix LED shield can use the LOLShield library from Jimmie Rodgers:http://jimmieprodgers.com/kits/lolshieldwith two modifications. The number of rows is different and the LED mapping is different.

You can download a premodified version of this library here:
