@bamfic pic3 might be an antenna?

re: AWS conference spyware device 

@riking That square-wave looking thing is definitely an antenna; seen them in all kinds of devices. C and D pads look like "clock" and "data", possibly i2c. What I don't know is:

1) What microprocessor is it?
2) What frequency/band does it operate at?
3) What does it, like, *do*?

re: AWS conference spyware device 

@bamfic @riking @rey Immediate suspicion based on the package marking: a Nordic RF device. They make all sorts of microcontrollers that do wireless things. Mostly in the 2.4GHz ISM band.
Went looking, found this: twipu.com/cybergibbons/tweet/1
My bets are on BT-SMART (aka BLE) indoor positioning / location beacon stuff.

I guess it's a custom part close to the nRF51802: nordicsemi.com/Products/Low-po
Possibly an ARM Cortex-M0.
Usually silicon vendors will castrate features out. So likely is missing some of the features that the 51802 has. Maybe only speaks BT or doesn't have AES or smaller Flash.
The chips get 'binned' and if something is broken / doesn't pass, it gets disabled by blowing a 'fuse'.
