An inertial measurement device includes a sensing module including a support and a measuring circuit board, a housing containing the sensing module, and one or more damping units arranged between the sensing module and the housing. The support includes a plurality of external surfaces facing away from one another. The measuring circuit board includes a plurality of panels configured to be bent along edges of the support. Each of the plurality of panels includes a front surface that (1) supports one or more electrical components and (2) faces an external surface of the plurality of external surfaces of the support. A gyroscope and an accelerometer are positioned on at least one of the plurality of panels facing a corresponding external surface of the support.
