A portable electronic device, such as a portable computer, a personal digital assistant and a mobile telephone handset, includes a main board module having opposite first and second sides, and a keyboard module mounted on and coupled electrically to the main board module. The first side of the main board module is formed with an opening and a keyboard receiving cavity that extends from the opening toward the second side. The keyboard module is received in the keyboard receiving cavity and is capable of being pulled to extend out of the keyboard receiving cavity via the opening. As such, other control devices, such as a touch control panel and a pen input panel, can be provided on a third side of the main board module that interconnects the first and second sides.
