ASD2421-R

    7 SEGMENT DISPLAY TINYSHIELD ASD2421-R     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.
