Electronic device capable of being flexibly configured with modules of different specifications

An electronic device capable of being configured flexibly with modules of different specifications, comprising:

• a main body, having a slot opening formed at a front end of the main body, a slot space communicated with the interior of the main body, a plurality of slot rails disposed on at least one sidewall of the slot space of the main body, a plurality of module slots communicated with the plurality of slot rails respectively, and the slot rail including at least one slot rail protrusion or a slot rail recession;
• and
• a modular device, including a plurality of electronic modules, each electronic module having at least one module rail slidably coupled to the slot rail, and each module rail including at least one module rail recession or a module rail protrusion;
• wherein the module slots in the slot space are configured to be corresponsive to the module spaces respectively, and the module spaces serve as a plug-in space of the electronic module, and the module spaces are communicated with one another;
• wherein the main body has a rear panel a circuit board installed on the rear panel a first connector installed on the circuit board, and a second connector installed at a rear end of the electronic module;
• and
• wherein the module slot has a slot edge disposed on both sides of the module slot separately and a slot connecting edge with twice of the distance is formed by two adjacent slot edges, and the electronic module has a module edge disposed on both sides of the electronic module separately.
