Technical fact sheets for Wacom signature devices

First go to Wacom Products for Business and select either "Signature Pads" or "Pen Displays" from the "Products" drop-down menu.  

Underneath the image of each product there is a "Full details" link which displays another page with more detailed information; part way down this second page there is a link to download the product's datasheet.

In addition, the CE certificates for all the products are available at https://www.wacom.com/en-us/support/product-support/drivers.
