FIELD: information technologies.
SUBSTANCE: data input device is made as a configured system of attached modules formed by a body as a basic module and separate functional modules attached to it by means of electric and mechanical interfaces. A body equipped with an interface of communication with an electronic device includes a front part with a keyboard segment and a rear part with a support surface for an arm, which form a ledge, where a set of keys is located, and at least on the surface of one side of the rear part there is at least one key or a trackpad. The basic module is equipped with pairs of electric and mechanical interfaces on sides of the rear part, on the upper surface, front and rear sides of the front part of the basic module and the support unit for a palm on the rear side of the basic module with the possibility of its disconnection, a keyboard segment on the front part of the basic module is a keyboard module attached to the upper surface of the front side using electric and mechanical interfaces.
EFFECT: expansion of functional capabilities of a data input device by using a system of connected modules, its increased usability.
