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.

    Nice LITTLE display

    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.
