CIRCLE EDGE LED TINYSHIELD
ASD2412-R-LA
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.

the TinyShield Compatibility Matrix.
LED Specs
o 21 Side Mounted LEDs around the side of the board
o Charlieplexed IO on 6 signals
o Available in Green, Amber or Red
TinyDuino Power Requirements
o Voltage: 3.0V - 5.5V
o Current:
o 1.5mA per LED (3.0V)
o 5.0mA per LED (5.0V)
o Due to the low current, this board can be run using the TinyDuino coin cell option
Pins Used
o Pins 4, 5, 6, 7, 8, and 9 are used, see schematic or sample code for connections
Dimensions
o 20mm x 20mm (.787 inches x .787 inches)
o Max Height (from lower bottom TinyShield Connector to upper top LEDS): 3.31mm
(0.130 inches)
o Weight: .73 grams (.026 ounces)
NOTES
o 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.
o 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.
o 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.
