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 an easy to use library is provided to make it extremely easy to use.
