Abstract: This disclosure relates to an inertial sensor, and to the field of embedded designs. The inertial sensor includes at least one inertial measurement unit; a controller configured to read measurement data of the at least one inertial measurement unit, wherein the at least one inertial measurement unit is couplable to or decouplable from the controller; and a plurality of sets of interfaces, wherein each set of interfaces has a first end electrically connected with the controller and a second end electrically connected with one of the at least one inertial measurement unit.
