A wired drill pipe electronic device includes a housing having a threaded connection at each end configured to couple to a wired drill pipe having double shoulder threaded connections. A chassis is disposed inside the housing and is configured to define at least one sealed atmospheric chamber between the chassis and the housing. The chassis defines an internal passage therethrough. The device includes a stress coupling to enable transmission of at least one of axial and torque loading from both the inner and outer shoulder of adjacent wired drill pipe segments through the housing.
