Rockbox SandiskE200HardwareComponents wiki page gathers all details and HW knowledge.
Here's pictures of my Sansa e260 internals. I had to use my digicam since my scanner isn't really good enough for this kind of task. I think the pics have details enough to at least be interesting.
There are additional photos on the e260 dev board page.
The flash chips (shown below) are located on the separate tiny daughter
board to the very right. As I pointed out in the wiki, the numbers of my chips
are interesting when comparing with the 6GB and 2GB models, as it seems the
'16384' chip is 2GB while the 4GB one seems to be marked '32768'... (and yes,
the pic shows my fingers and tool since I didn't want to remove the plastic
pad completely but just pushed it gently for the photo to catch the numbers).
The number would then match megabits of course. 32768/8 = 4096 and 16384/8 =
