Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

any decent AVR can support a ram upgrade. you can access it natively, at the same speed as onboard ram, at the cost of 16+3 pins. maximum size is 64K, iirc.there's no easy way to hack into a pen drive, except, perhaps, desoldering the storage IC and soldering it on your board. Your best bet is to connect to a SD card, which uses SPI.
Sounds great. I guess I'll just see how I go with the 4GB that comes with it, and if I need more RAM or HD I can buy an SD card and some RAM. Thanks for the help guys!
4Kb of EEROM is a large amount of storage on a microcontroller. i have never needed more than 50 bytes in any of my applications.the EEROM is not used for storing programs. they use the onboard flash memory.
I'm hoping to be able to use it's to identify and remember faces
