Abstract: A stackable board-to-board module connector is mainly composed of a main module unit, at least one accessory module unit, several first terminals and second terminals. The main module unit combines with the accessory module unit to form a connector. The main module unit can be a standard device, while the accessory module unit can be an independent device that serves as a stackable accessory to adjust the height according to the total height requirement of board-to-board module connector. Through such a main module unit or a stack of several accessory module units, various height specifications can be achieved for a board-to-board module connector. In other words, it only needs to change the number of the accessory module units embedded in the bottom of the main module unit, the height requirement for a board-to-board module connector can be met. By this means, it is not necessary to prepare molds repeatedly.
