I am considering getting Gumstix for a project and I have two questions:
1) I see under the Support page on the website that there are some wordings
battery powered Gumstix (like 3 AAA batteries). But everywhere on
Gumstix website suggests using power adapter. Is there a version of
Gumstix that can be battery powered? If so, can you tell me the link
to that version of Gumstix?
2) I see that there is an expansion board that does GPS. Is there an
expansion board that can do GSM/GPRS?
