    The 16 Edge LED TinyShield allows some cool and easy LED indications using only five I/O signals. The 16 LEDs are mounted around the outside of the board, and can easily be seen even when the LED board is in the middle of a TinyShield stackup. 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.

      • Charlieplexed IO on 5 signals
      • Available in Green, Amber or Red

      TinyDuino Power Requirements

      • Voltage: 3.0V - 5.5V 
      • Current:
        • 1.5mA per LED (3.0V)
        • 5.0mA per LED (5.0V)
        • Due to the low current, this board can be run using the TinyDuino coin cell option

      Pins Used

      • Pins 5, 6, 7, 8, and 9 are used, see schematic or sample code for connections


      • 20mm x 20mm (.787 inches x .787 inches)
      • Max Height (from lower bottom TinyShield Connector to upper top TinyShield Connector): 5.11mm (0.201 inches)
      • Weight: 1 gram (.04 ounces)


      • If the top connector is not needed, there is also the Circle LED TinyShield which has LEDs that circle the entire board.  
      • The LEDs are hooked up using Charlieplexing, a technique for driving many LEDs with only a few IO signals.  See the tutorial to learn more about this and use our free library to control these easily.
