Wroking great with my Arduino Uno! The built in potentiometer is really nice addon.

Great product, used in on the UNO and everything just works perfectly without even setting the contrast. This eliminates a lot of wires connectlng a single LCD.

This unit works better than I thought it would. The select button on mine is a little bit flaky, but the resistor cascades on the buttons are more accurate than I expected. analogRead(A0) returns consistent values down to the 10th bit when a button is pressed.
The D10 issue that had plagued some versions of the LCD displays has been addressed and fixed.
The display is insanely simple to write to. The supporting links supply all the info necessary. It took all of 10 minutes to get it working.

Works, but seems a bit touchy. All of the buttons are connected to a single analog input and just provide different voltage levels, so I had to tweak things to get my Left and Select buttons to be recognized correctly. And, there’s no reasonable way to recognize two buttons being pressed at once.
Also, if you touch the PCB of the shield in the wrong place, it shows garbage on the LCD until you reset the Arduino.
