Works perfect. It's nice not having most of my I/O pins occupied for the LCD.

Really great product!  Is there a Mechanical Drawing to get exact dimensions on the mounting holes?

Big, nice looking display May 21, 2015
By: FM3 from Seattle, WA United States  
I have this running on a MSP430F5529 LaunchPad using Energia. It was easy to set up and it makes for an easy reading display.   The LaunchPad is a 3 volt device and the display is 5 volt so it is necessary to translate voltages. I used 2 BS170 MOSFETs. This is not necessary with 5 volt Arduinos - they are even easier to set up.
