I am new to gumstix and somewhat not that experienced with embedded systems. We like to develop a prototype with communication and positioning abilities.
Our requirements are
•Mobile connection (GPRS or/and UMTS)
•GPS - Not the best but not the worst
•DO - 4
•AO - 2
•AI - 2
•Static camera ability in some way...

What modules do I need from gumstix? I think the product range is hard to brows for a newbee.
