Sometime you just need a numeric 7-segment LED display in your project. Here is one that is suitable for up to 8 display modules and uses only nine lines to interface to the display. The driver module is connected to the microcontroller with only 3 signal lines. Just add +3.3V and ground and a few external components and you are ready to go. More information available at:
