    Abstract: A portable electronic device includes a housing defining an internal volume and a circuit board assembly within the internal volume. The circuit board assembly includes a first circuit board, a wall structure soldered to the first circuit board, and a second circuit board soldered to the wall structure and supported above the first circuit board by the wall structure. The second circuit board defines an exterior top surface of the circuit board assembly. A processor is coupled to the first circuit board and positioned within an internal volume defined between the first circuit board and the second circuit board and at least partially surrounded by the wall structure. A memory module is coupled to the exterior top surface of the circuit board assembly.

    Abstract: Embodiments describe a portable electronic device that includes a housing having an interface surface and an inductor coil disposed within the housing and comprising a conductive wire wound in a plurality of turns about a center point and in increasing radii such that the inductor coil is substantially planar. The portable electronic device further includes charging circuitry coupled to the inductor coil and configured to operate the inductor coil to wirelessly receive power and wirelessly transmit power, control circuitry coupled to the charging circuitry and configured to instruct the charging circuitry to operate the inductor coil to wirelessly receive power and to wirelessly transmit power, and a device detection coil coupled to the control circuitry and configured to detect the presence of an external device on the charging surface, the device detection coil is configured to operate at a different frequency from the inductor coil.
