Connecting a hand-held device to peripheral devices

A peripheral module for a hand-held computing device having a device electrical port at a device surface thereof, comprising:

• a first electrical port receiver at a first surface of the module, configured to mate with the device electrical port of the hand-held computing device;
• a first peripheral electrical port, of substantially identical shape and electrical functionality to the device electrical port, at a second surface of the module, opposite the first surface, which first peripheral electrical port is available to mate with a further peripheral module having a second electrical port receiver that is also configured to mate with the device electrical port of the hand-held computing device;
• and
• circuitry, coupled between the first electrical port receiver and the first peripheral electrical port, which is adapted to carry out an application function in association with the computing device while the first electrical port receiver is mated with the device electrical port of the computing device.
