As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
I found the DFRkeypad library in the Arduino list and installed it. It more or less worked, though the keypad code is a bit rough. The display worked out of the box, and I really like the programmable backlight level.

Thanks Robert for the tip about changing the initial pin numbers. Hello World!

Works great with MPJA UNO once sketch changes are made.
Most of the LCD test sketches use different pins that dont allow this 1602 LCD shield to function when plugged directly onto the UNO board. Change the initilization line to:
LiquidCrystal lcd8, 9, 4, 5, 6, 7;
and the basic 1602 LCD test sketch should run correctly with this shield.
Im a new Arduino user and having fun with MPJAs UNO and additional hardware options. I rate this LCD as 4 star only because it is not directly plug and play.
