h1. Hardware h2. 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.
