and according to Sandisk it can stream media for several hours to several clients simultaneously, on a single battery. It would be cool to have a pocketsize server, actually working in your pocket, wouldn't it?
I failed for that goal, but as Google failed in finding any inside information about this gadget, I decided to share my findings anyway.
The stick isn't glued together. Using some persuasion (a blunt knife) I could open the housing without cracking anything. To my surprise there is a micro SD card inside. Unfortunately the most interesting parts (ram and SoC) are inside a metal housing, (left on the photo) which I couldn't open without damaging the whole thing. BTW, that small diagonal line left of it is the Wifi antenna.
The stick is hiding a part of the SD card.

1041075 0xFE2B3 HTML document footerThe most disappointing part is that the dumpfile (16MB) doesn't contain any more data than the downloadable firmware file (1MB).
Both can be gzipped to 660KB. So unless there is also some flash memory in the metal box, this stick isn't running Linux. 660KB is simply not enough.
That doesn't mean the box can't run Linux, that will depend on the amount of RAM memory, and the used SoC. Unfortunately I don't know either of them,
due to that metal box. And I couldn't find a serial port either, although there are some interesting pads on the backside of the PCB. Maybe the OS doesn't show a bootlog? My oscilloscope didn't see any signal on either of them during boot. (Which is blazing fast, btw. About 2 seconds.)
So, for now I have parked the project. I uploaded the dumpfile here. Maybe someone with a died SD card can use it to revive his 'Sandisk Connect'.
