arLCD ezLCD + Arduino Uno = Touchscreen Magic! There is no easier or more cost effective way to have a touchscreen LCD in your Arduino project. Get a touchscreen LCD project up and running in minutes, not days! Easy to use via USB development cable (included) and your PC. The ArLCD is easy to program using the Arduino IDE and the Arduino ezLCD library. The EarthSEMPL (Simple Embedded Macro Programming Language) API is enjoyable to use and intuitive! A multitude of fonts, images, widgets and sample macros are included to get you going quickly! Widgets include: analog meter, buttons, checkbox, dial, radio button, slider, and others! Do not confuse this with a snails pace 2.8" LCD shield that uses almost all your I/O pins! This is a full smart ezLCD GPU with the Arduino Uno R3 on the same PCB in a thin easy to integrate package with a panel mount bezel available in the near future. The 3.5" has 64% more display area then a 2.8" LCD. The ArLCD combines the Arduino and the award wining ezLCD into a single product ready to accept all Arduino compatible shields! Product Specifications: Arduino Uno R3 Compatible 3.5" color TFT LCD 320 x 240 Resolution 65k colors LED backlight 500:1 contrast ratio Touchscreen Powerful 16-bit GPU 4MB flash memory for storing fonts, bitmaps & macros USB 2.0 Overall outline dimensions: 3 x 3 x .9 inches 6-9V operating voltage Extremely low power - draws less than 200mA -20 to 60°C Operating temperature RoHS compliant EarthSEMPL (Simple Embedded Macro Programming Language) Operating systems: Windows 7, XP, Linux, and OSX

Good that it is NOT in stock!!!
An absolute NIGHTMARE to program. I would not recommend this product to anyone. WAY over priced!

Wonderful unit, lousy documentation
This is an awesome unit. I have interfaced other displays to an Uno through SPI and in addition to the tangle of wires they have been a little slower than I'd like. Having the Uno attached and hardwired right to the display is genius. The Uno is a clone and it has a mini-B instead of a B USB connector but EarthLCD includes a nice long cable. Another great idea is the built-in 4MB flash drive. When you plug this into your computer the drive mounts and it includes the Arduino library plus documentation. You can copy graphics and fonts to the drive and then use them on the display. Another minor difference is that when you program the Uno (using the normal Arduino software is fine) you're actually talking to the GPU in the display. It then relays to the Uno. It looks the same except that a new driver will install on your computer when you first connect it. You may need to get that from the EarthLCD website. Or you may not...see the next paragraph.I'm taking one star off because the documentation for this unit is terrible. I'm not sure if it's a company name change or a new company but they mostly moved from earthlcd.com to earthmake.com for support. Both websites exist and there are various links in the documentation pointing to wrong places. And links to software that doesn't seem to exist. I found one document warning me to update the firmware. I couldn't actually get that process to work and finally figured out I was already at the proper version. I also wasted a little time trying to "install" the Windows driver but, again, in the end I didn't actually need to do that.Sparkfun used to carry this unit and you can still see (but not order) it on their website and their quick-start guide turned out to be more useful than anything I found on the earthmake site. There is documentation included on the built-in flash drive as well. It's just not very readable.As for programming it, thankfully the examples in the Arduino library cover most of the capabilities of the unit and reading that code is probably the most effective way to figure out how to use it. I recommend not fretting over how to upgrade it though. 2.10 is the latest version of the firmware as of April 2015.
