Source for small (e.g., PDA/phone) color touch panels

From: D Yuniskis on 17 Feb 2010 17:29 Hi, I am looking for 10 - 20 small-ish color LCD touch panels for a "one off" project. In these small quantities, I suspect I may be better off purchasing a bunch of "appropriate" PDA's on eBay and cannabilizing them for parts (?). That could also be a win as the MCU therein already has support for driving the panel (so, I could just "talk to" the MCU instead). Suggestions? Alternatives? Panels must be backlit and work with "finger" touch (not require a stylus). Thanks! --don

Not sure on availability, and I haven't used it myself, but it was pretty cheap at one point ... has touch screen, usb, and MEMS accel. ... ??? Cheers, Rob Sciuk

I suspect I can find abandoned PDAs for considerably less. Problem will be getting enough of them without having to pay S/H "per each". Then, worrying about the quality of their individual screens (wear patterns). Thanks!

Been there done that for a project and after one and half year when the need for three more parts arrived I almost went crazy to obtain the additional ones! my 0.019999.... -- Cesar Rabak GNU/Linux User 52247.
