Abstract

A bluetooth converter of an input device has a micro-controller unit (MCU), a first-protocol connection port, a second-protocol connection port, a protocol signal converter and a bluetooth unit. The first-protocol connection port is connected to an input and output (I/O) terminal of the MCU. The second-protocol connection port is another I/O terminal of the MCU through the protocol signal converter. The MCU is further connected to the bluetooth unit. When a wired computer input device is connected with the first-protocol connection port or the second-protocol connection port, the output signals can be wirelessly transmitted to a paired computer through the MCU and the bluetooth unit so that the wired computer input device can be converted to wirelessly input data to a paired computer compatible with a specific protocol.
