DESCRIPTION

The TinyShield 7 Segment Display Board contains two seven segment LEDs (Red LEDs) that can be set over the I2C (thus saving signals to do other tasks) by using a Semtech SX1506 I/O expander. Each of the segments including the decimal indicator can be individually selected, and a library is provided to make it extremely easy to use.

Display Specs

• Two Seven Segment LEDs, Color Red
• Displays include decimal indicator
• I2C Semtech SX1506 I/O Expander 

TinyDuino Power Requirements

• Voltage: 3.0V - 5.5V 
• Current:
• 4mA per segment (3.0V)
• 10mA per segment (5.0V)
• Due to the current, this board can run for a very short time on the TinyDuino with coin cell, however a Lithium battery should be used for longer life.  

Pins Used

• A5/SCL - I2C Serial Clock line
• A4/SDA - I2C Serial Data line

Dimensions

• 20mm x 20mm (.787 inches x .787 inches)
• Max Height (from lower bottom TinyShield Connector to upper top of LED displays): 6.6mm (.26 inches)
• Weight: 1.36 grams (.05 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.
