Pulling this mess out is a destructive procedure, but after ripping out some soldered connectors we get our first real look at the S1.
Despite rumors (and hopes) of an upgradable product, the difficulty of removing the S1 alone casts serious doubt on the idea of simply swapping out the internals.
Unfortunately, our first look is obstructed—that S1-emblazoned silver cap isn't a cap at all. It's a solid block of plasticky resin, hiding treasures deep within.
Update: Chipworks has identified this small IC as the STMicroelectronics C451 gyroscope + accelerometer.
