For those of you who have questions on the Ardino At Heart certified arLCD ask me here on the forum. I've had one for six months and if I cant answer your question I will find someone who can!
My question has to be simply "What is it?"
Ok so according to Sparkfun it's a touch screen integrated with an Uno. But the page goes on to say it's Uno compatible.... how does that gel with it saying the Uno is built-in?
Does the built-in Uno just drive the screen and you still need another one for the rest of the project?... or what...
For $90 it better have an UNO built in. The photos are too small to see any connection detail but it looks like there is a label covering the right side of the unit that could be like a shipping label. It's possible there are screw terminals underneath the label. Here's a YOUTUBE video on it:
It looks like the UNO and the touchscreen are back-to-back on the mounting plate so you have access to the arduino headers on the back. Robert
It's an arduino plus touchscreen that only uses 2 pins. There is also a dedicated chip for the touchscreen and a flash drive for pics and fonts. It can show meters, sliders, etc. Check the arduino blog for more info. It only uses one arduino.
I have a case on Thingaverse.com if you are interested.
