Schematic for HL Series and AT/Ex AT Commands

I have a link to the HL development kit pdf, but the schematics are blurry. Is there a link or a document that you can attach to this? Also, both of AT/Ex AT commands documents cannot be found on the website.

Can you send updated links for the source.sierrawireless.com?

Thanks!

The AT command guide is here:
