Abstract:
1. An extension module connectable to a baseboard comprising a first connector, the extension module comprising: a plurality of circuits to process periodic signals and to control the circuits processing periodic signals at a variation timing of a signal within a constant period; and a second connector connectable to the first connector of the baseboard for connection to the baseboard, the second connector comprising at least one second terminal suit, the at least one second terminal suit comprising a second ground terminal connectable to a first ground terminal of the first connector, a second source terminal connectable to a first source terminal of the first connector, and a second signal terminal connectable to a first signal terminal of the first connector, wherein the plurality of circuits are stackable and configured such that a signal from the second signal terminal of the at least one second terminal suit sequentially controls the operation of the plurality of circuits to process periodic signals within a constant period.
