Abstract

An expansion apparatus with a network module mainly has a circuit board, and a signal output port, a central processing unit, a memory unit, and a network module which are electrically connected on the circuit board. The memory unit stores an operating system, and the operating system is executed by the central processing unit after the expansion apparatus is started up. The expansion apparatus is substantially a small computer. The signal output port is provided to connect to an external display screen to output video and audio signals generated by executing the operating system to the display screen and displayed on the display screen. The network module is electrically connected to the central processing unit to provide 3G, 3.5G, or 4G-LET network connection functions. Accordingly, the expansion apparatus is used to be a small computer with a network connection function.
