Member Rob, completed his LED display shield project for his Launchpad. His shield holds the NFD-5641, a four digit numeric display connected via a 74HC595 port expander.

Here is a little LED Display Shield I have created for LaunchPad.
It has 2 595’s, uses 3 wires to communicate with LP, and supports both, common anode and common anode displays.
All LP’s pins are accessible on the shield, any pin can be used to drive the display.
Four unused 595 outputs are also accessible.
Transistors are MMBT3904 NPN for CC (R14 0ohm and R13 empty) or MMBT3906 PNP for CA (R13 0ohm and R14 empty.)
