Freetronics 16x2 LCD Shield required pins

Post by Gusto » Thu Sep 18, 2014 12:43 pm

Hi all,
Other than the digital pins 4 to 9 and the analogue 0, what pins are required to be connected on the Freetronics 16x2 LCD?
I may have got a bit excited and cut off all the other pins and now the display doesn't work.
Thanks

You need D4~D9, A0, 5V, and GND.
If you're curious the schematic and design file links can be found at the bottom of:

Thank you,

It seems obvious now that it would require a 5V and GND connection but the features for the shield says that "Pins used by shield clearly marked" so I just left the marked ones alone and cut the others off.

I will re-attach the 5V and GND pins...
