For all the Arduino microcomputer addicts who love tinkering around on really cool projects, here's something that will might help you bring those projects to the next level. It's the ArduinoLCD from EarthMake, and it offers an affordable way of integrating a touchscreen into your latest gizmo.

The ArduinoLCD is a 3.5-inch touchscreen with 320 x 240 resolution. Obviously, this is not going to blow anyone away with stunning HD visuals, but it will work fine for most projects. It has a 500:1 contrast ratio, which should create good blacks on the screen. The screen is also LED backlit, so it will be plenty bright, and is capable of displaying 65,000 colors.

The touchscreen features its own 16-bit GPU. It also has 4MB of internal flash memory designed for storing macros, fonts, and bitmaps. Conveniently, it comes with a mounting bracket, which should make it easy to integrate into your projects.

One of the main features that makes this screen an attractive option for Arduino users is the low power consumption. The device is rated at six to nine volts for operation and it draws slightly less than 200mA.

Interested users can preorder the device now, and it is scheduled to ship on November 11. The current retail price for the ArduinoLCD is US$79. EarthMake is calling this an "introductory price," so it could go up by the time the screen officially launches.

"Introductory" price? It had better go down or they'll go out of business, IMO. Weaseling on pricing is not a good confidence builder and is uncompelling as far as anyone's make/buy decisions go.

There are touch color LCDs under $50 (qty 1) right now that are Arduino compatible that just need a firmware driver and cable (or "shield" if you must).


I love it! I'm building a whole new app with Arduino and as a busy open source developer I need all the help I can get. This saves so much time and puts me ahead of the curve with the big boys.

Thanks Arduino, what's next I can't wait.

A shield takes most of your pins and cpu resources. ArduinoLCD has a separate GPU that means a CPU for just running the LCD! This has the arduino on the same board. And this is much thinner then an Arduino with a shield. Actually a lot of technology for $79. This was one of the coolest new products at Maker Faire. I think EarthMake has a hit on their hands.

Jeff, the ArduinoLCD is not made by the official Arduino team.

Also checkout the 4D systems LCD modules with on board GPU. Along with GorillaBuilderz LCD shield for Arduino and open source GorillaBuilderz Arduino libraries.
