Customizable wireless device having stackable modules

Abstract

A wireless device such as a wireless telephone includes stackable modules. Each of the modules provides an independent wireless device function. Each of the modules stacks onto and connects to at least one of the other modules. Each of the modules includes a communications contact connected to a communications contact of at least one of the other modules. Each of the modules also includes a power bus contact connected to a power bus contact of at least one of the other modules. The modules include a memory module, a flash memory module, a read only memory (ROM) module, a random access memory (RAM) module, a central processing unit (CPU) module, a display module, a keypad module, a transceiver module, a battery module, a global positioning satellite (GPS) receiver module, and the like. Each of the modules includes keying patterns to ensure that the modules are connected together in a proper order.
