7 Segment Display TinyShield (Discontinued)
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.

Customer Reviews
I am not using this display with the whole Tiny ecosystem of parts. I just needed a small I2C display to be part of a heads up display for a GoPro type action camera. This was the right size for what I was looking for. (An LCD/Oled or other display has a problem in that the display is rasterized and suffers from rolling shutter effects when seen by a camera). I only wish that the display had 4 holes of even just pads for the prime signals so that I did not have to include the proto board in a stack. Yes I can find places to tack wires to, but it is not the same. Also notice that the I2C to GPIO chip is no longer available if that matters to you.
