DESCRIPTION

The Circle Edge LED TinyShield uses only six I/O signals to create a wide variety of LED indications. This board includes 21 LEDs that are mounted around the outside of the board to form a full circle. It's designed to be placed on the top of your TinyShield stack. The LEDs are arranged using Charlieplexing, a technique that allows for control of multiple LEDs using fewer I/O signals. Available with Red, Green and Amber LED color options.

LED Specs

21 Side Mounted LEDs around the side of the board
Charlieplexed IO on 6 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 4, 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 LEDS): 3.31mm (0.130 inches)
Weight: .73 grams (.026 ounces)

NOTES

This board has no top TinyShield connector, so no additional TinyShields can be stack on top of this. This board is meant to be on the top of a TinyDuino stack.
If a top connector is needed to stack additional TinyShields, there is also the 16 Edge LED TinyShield which has 16 LEDs and a top connector.
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.
