1. An inertial sensor, comprising:
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;
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; and
one or more sets of reserved interfaces, each set of reserved interfaces comprising a first end and a second end, the first end of each set of reserved interfaces electrically connected with the controller, wherein:
under a first specified condition, the second end of the one or more sets of reserved interfaces is not electrically connected with any of the at least one inertial measurement unit; and
under a second specified condition, the second end of at least one set of the one or more sets of reserved interfaces is electrically connected with a newly added inertial measurement unit other than the at least one inertial measurement unit.
