<p>The present invention relates to a scalable 3G gateway M2M device by a block. An M2M device by the dynamic configuration of a hardware interface pin includes a main body part which receives the request of an M2M application part and changes an interface pin; and a block type extension part which is a block type which is extended and combined with the main body part, and extends the function of the main body when fixed to the main body. The main body part includes an interface pin part which is a pin assembly basically installed to a terminal, and is set with a basic value at an initial stage; an interface pin change part which changes the pin of the interface pin part; an M2M application part which is an application part operated in a terminal, transmits a request signal to the interface pin change part for using a specific external hardware interface pin, waits for the response signal of the interface fin change part, and then uses the external hardware interface pin; a connector part which is connected to the interface pin part and is connected to the block extension part having the hardware interface pin; and a pair of female fixing parts which have a space for inserting the male fixing part of the block type extension part, are exposed to the upper and the lower side based on the connector part, and are fixed to the male fixing part.</p> |
