Cool PCB guys and I love the wheel. Two thumbs up!

I've taken the liberty of labeling everything that I could.
THIS IS JUST AN EDUCATED GUESS!!!
I'm pretty sure I'm correct on most of it.

You missed the mini - usb connecter, but cheers

Just thought I'd let you know that there's no external ram or flash, so those guesses were completely wrong. I also doubt Michael has used a RS-232 level convertor (not everyone is going to use the uart, so it seems a bit daft to spend the cash on the convertor).Kevin_H said:

Nothing good will ever come of Exophase.
I dunno about the chips at all, but some other things that I haven't seen anyone point out, that I think are likely guesses:
- lower left, to the right of the volume dial is a power switch
- upper left and right corners are shoulder buttons
- connector to the right of USB host is power input

There is external Ram and flash, I forgot the ram sits on top of the CPU, but if you look at the spec sheet for the OMAP, it doesn't have any internal Flash. So a flash chip is needed to store a kernel image or at least a simple SD card bootloader.Squidge said:Just thought I'd let you know that there's no external ram or flash, so those guesses were completely wrong.

Second I believe that the RS-232 converter is for Debug and board bringup purposes, it will be removed once the design has been proven.
What I labeled as EXT Ram is most likely the LCD controller. (I thought the LCD controller was internal and the Ram was external, I probably should have looked at the spec sheet first for the OMAP)

Says What?
Did someone grind the numbers off those chips?

My post wasn't phrased in the best way, by "external" I meant somewhere else on the board. Both ram and flash are actually on top of the omap (It's a combined ram+flash setup, not seperate chips for each).Kevin_H said:
Now thats a possibility.Kevin_H said:
The LCD controller *is* internal. However, the omap can't drive an LCD directly, therefore a buffer is required.Kevin_H said:

Don't be too harsh on the guy, he's only tryna help us electronic noobs.

I didn't know that the flash was included in the ram chip, thats pretty sweet. The team is pretty lucky that this is TI's pet project otherwise parts like the RAM/FLASH chip and CPU would be pretty dam expensive in low quantities, if not impossible to get.Squidge said:

Yes, no, I, this is.
Yeah, it all looks nice. I'm looking forward to seeing all of that silicon and plastic actually do somethingargor said:nice pixs
and @ Squidge congrats on being a new mod
hope you don't let the ban power temp you
(Oh, and congrats Squidgie.)

I thought Squidge had a different avvy. But no one was mentioning that he was a mod, so I thought that maybe you could have that avvy and still not be a mod or something.argor said:and @ Squidge congrats on being a new mod

Yup, I know. I just wanted to make sure people didn't get the idea that they could remove that chip and replace with a bigger one to get more memory.Nova said:
As for the small square chip below the omap cpu, it should be one of these:
