Looking for the writing module in graphic board

Hi,

I am finding the writing module in graphic tablets for project,
but it seem to be not available on market or hard to find...

I did several research on internet but cant find the stuff.

Maybe i need should bought a new board and remove the module ..


So, is there are writing modules ( somethings recognize the drawing) available on market?

Handwriting recognition is usually done in software, using whatever touchscreen is available as an input device.

I see, besides Handwriting recognition, i want to draw something like function of graphic tablets

and send to computer wirelessly, so the writing modules is required, do you know where can i buy it?
