Referring to fig. 1-6, a data expansion module includes: a shell 1 and a first data interface 2; a first data interface 2 is arranged on one side surface of the shell 1; a data transmission contact 5 is arranged on the first data interface 2; the first data interface 2 is provided with a first magnetic attraction component 4 for fixing the first data interface 2.

Specifically, the housing 1 is a band-shaped housing. Preferably, the housing 1 is a rectangular housing.

The housing 1 may also have other shapes, such as a circle, a triangle, etc., and it is necessary to ensure that the housing 1 connected to the first data interface 2 is a plane, so as to ensure the flatness of the first data interface 2.

Specifically, the first data interface 2 is connected with a flash memory chip 3 arranged in the housing 1.

The first data interface 2 is connected with the flash memory chip 3 in the housing 1 in a conventional manner.

Specifically, the first data interface 2 is attracted to the second data interface 7 through the first magnetic attraction component 4.
