I have an LCD keypad shield from dfrobot:

It looks like it's supposed to just plug in on top of an Uno.
Can anyone advise on how to use this with a Moteino USB?
Thanks.
Hi Neddie,
This is designed for the UNO and that's likely why it's 5V and has specific connections. All moteinos are running at 3.3V so you may need voltage buffering between the 2.
If at all possible I would recommend using 3.3V LCDs with Moteinos since it requires less parts.
I like the popular nokia 5110 LCD, used in the MightyHat kit and I plan to put it up in the store separately as well when I get a chance.
Otherwise the UNO is probably a little easier to get started with for absolute arduino beginners, but it will also have difficulty with any sensors and radios that run on 3.3V.
Thanks Felix, very helpful.
You can just use the 5V pin of something like a Power Shield 500c(PS500)- just attach the 5v and the GND of the PS500 to the Moteino's VIN and GND, respectively.
