We are sorry the description is wrong, Please pay attention this is Common Cathode ¬† This is a 16 segment common cathode LED and is blue. The advantage of 16 segment is that you can not only display 1234567890, but also ABCDEFGHIJKLM. ¬† It is compatible with bread board and can work with Arduino by adding some current limiting resistors. So, it Suitable for people who is newbie of electronic. ¬† Note: It just a segment LED without control chip. ¬† Features High Light low current low-voltage low energy Longevity IC-compatible ¬† Specification 0.80 inch common port: 11 size: 20.0 x 27.7 x 8.5mm Colors: blue surface colors: Black Working temperature: -20~60¬įC ¬† Mechanical Outline?
