On the other side

This clear place on the PCB is for the antenna on the other side

nRF52832 BLE chip (maintains the only wireless connection of this device)

This is a tiny temperature sensor (not sure which one exactly)

The metal connector is a smart way to reinforce this tiny PCB

The sensor is on the edge, but still inside plastic case, and has no thermal channel to the outside (no vents or compound) - this fact rises a huge concern about the speed of the measurements

No temperature + humidity combo here, as seen in the Thermostats... really, Nest?! I mean, for $40 I had higher expectations..

That's it. Thanks for reading! Post comments if you have any questions or suggestions
