h1. Hardware
h1. Physical Setup / Board Stacking
The hardware consists of two circuit boards:
* Top board: AC/DC power supply and Ethernet switch
* Bottom board: Actual Femtocell mainboard
The two boards are sandwiched together by the following connections:
* 6-pin fine-pitch connector (most likely for DC power)
* flexible printed circuit cable (most likely for Ethernet MII/RMII)
* two large sheet metal parts for ground and/or thermal connection
It is thus not very straight forward to operate the opened device in a safe way (i.e. without live AC line voltage present).
We will be working on a way to operate it with injected safe low DC voltage, but that is still TBD.
