An apparatus for protecting an electronics module used in a borehole includes a borehole string section having an outer circumferential surface on which at least one pocket is formed, a mount associated with the at least one pocket, and a sleeve surrounding the section of the borehole string. The mount includes a housing, a lid, and a biasing member. The housing receives the electronics module and is seated on a seating surface of the at least one pocket. The lid encloses the housing within the at least one pocket. The biasing member is positioned between the lid and the housing. The sleeve presses the lid against the biasing member and the biasing member may responsively urge the housing against the seating surface. Related methods include protecting the electronics module with the mount.
