I know people are saying this is a bit steeply prices, but I think this is perfect. I&#x27;ve been looking at the various options and they typically all require three components- the touchscreen&#x2F;lcd itself, a controller board of some sort, and then the Arduino itself. Then you have to actually put it all together, and as people have mentioned you end up with a lot more than two pins being used.<p>This one at Adafruit costs $40, uses five or six pins, is smaller and doesn&#x27;t have the Arduino built in.

On a side note, I like how the product is presented by two young girls. Is this intended for educational purposes?

&gt; 320 x 240 Resolution<p>Aside from the fact that&#x27;s for an arduino, which probably mean very low power available, does anybody knows why all those hobbyist LCD are so low in term of resolution?<p>It seem impossible to find something higher than VGA on mouser or even Alibaba, much less a reasonably priced HD screen. Where are all those glorious smartphone screen?<p>(I&#x27;m talking about small screen, but even larger one are not that much better)

It looks cool, but the price is a bit steep. You can get a touchscreen LCD from Adafruit at $39.95 (<a href="http://www.adafruit.com/products/1651" rel="nofollow">http:&#x2F;&#x2F;www.adafruit.com&#x2F;products&#x2F;1651</a>). You still need to buy an Arduino, but they&#x27;re cheaper than $45,-. I&#x27;ve bought Chinese Uno V2&#x27;s for less than $15 a piece.

Okay, how do they run that color picker sketch with only 2 KB of RAM available on the Uno? I tried to do some <i>string parsing</i> and it failed at 200 byte-long strings due to lack of memory, how can they show an entire picture composed of thousands of pixels?

I&#x27;m all for supporting small business that create hardware, especially open source (heck, I&#x27;m working on some stuff myself), but they must make an effort to make their products affordable. I can buy a 3.2&quot; touchscreen LCD for $12 in single quantities[0], shipped locally in the UK. The BOM for an Arduino is somewhere around $10 in single quantities. Their selling point about only using 2 pins? Yeah, shift registers or i2c I&#x2F;O expanders are <i>so</i> fancy...<p>[0] <a href="http://www.ebay.co.uk/itm/3-2-TFT-LCD-Display-Module-Touch-Panel-Screen-PCB-Adapter-240-x-320-Pixels-/331106884444?pt=UK_BOI_Electrical_Components_Supplies_ET&amp;hash=item4d17821b5c" rel="nofollow">http:&#x2F;&#x2F;www.ebay.co.uk&#x2F;itm&#x2F;3-2-TFT-LCD-Display-Module-Touch-P...</a>

Does anyone have any idea of what it will cost? I can&#x27;t wait to get my hands on one of these.
