DESCRIPTION

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.

LED Specs

• 16 Side Mounted LEDs around the edge of the board
• 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

Dimensions

• 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)

Notes

• 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.
