7-Segment Display - 20mm (Blue) COM-11408

I purchased a Sparkfun 7-Segment Display - 20mm (Blue) COM-11408 but did not realize that it did not come with a breakout board or other controlling device.

What additional Sparkfun product must I purchase in order to use this display with an Arduino UNO R3 type of micro controller?

I now see there are several 7-Segment Display boards that have the breakout board and display integrated as one unit (SparkFun 7-Segment Serial Display - Red COM-11441).

Can the standalone display I purchased be used with one of these types of products or is there a different board available that it will plug into?

Thank you for any guidance in being able to put my original purchase into an operating project.

There are a few possibilities here https://www.sparkfun.com/categories/359

You can make your own Arduino interface. You will need resistors for the anode connections to limit the current and four transistors plus base resistors for the cathode connections.

Thank you for the suggestions and accompanying JamesCo article. I will play around with some code and wiring to gain an understanding of how the 4 digit display works.

Thanks again.
