Here you see the bluegiga BLE112 module on a board with the shield still in place:
And here I removed the metal shielding can:
As you can see no real surprises here:
The central unit is a Texas Instruments CC2540 SoC Bluetooth Low Energy module.
On the lower right of it sits a 32 Mhz crystal for the main clock.
Above it is what I assume the 32.768 kHz low speed clock crystal.
The antenna was already visible with the can in place, but what's interesting is the second companion chip inside the can. I assume it is some kind of filter for the antenna.
Besides that just a few passives and that is it!
