PDA components

6 posts in this topic

I'm very interested on the internals of Cellphones/PDA's.

It's basically a PC with it's components somehow down-sized. I'm not sure of the correct term for it. (Microcontroller?)

Sizing down a wireless card is also impressive.

So how would you build a small device with a small wireless card, and have it run Linux?

Maybe the correct term is 'embedded device'. No clue.

You mean something like this?

Ah, yes. That's what I'm looking for.

Now how are these suckers powered? I don't see any kind of onboard battery here?

They usually take no more than two types of batteries.. One usually a Lion battery much like all cell phones, cameras, portable gaming units.. And then usually a tiny watch battery li-22 or a standard CMOS battery put back inside the arm..

SD and CFflash Wifi cards are common in some linux devices.. But most have built in IR, Wifi or Bluetooth which consume the batteries(Lion) like crazy
