The integrated control units of the SMD ‑ mini series of the second version are designed for use with two-phase hybrid stepper motors, which, when used together with the units, form non-programmable stepper drives of compact dimensions.

The SMD-mini blocks of the second version are the drivers supplying the motors in accordance with the external digital signals supplied to the control inputs.

The drivers provide the required speed and direction of rotation of the motor, as well as accurate positioning of the shaft by processing logical signals: PITCH (pulse), DIRECTION (level) and RESOLUTION (level). As a source of logic signals, frequency generators, PLCs, computers with an LPT port, etc. can be used.

The features of the drivers are microstepping mode up to 1/256 and software setting of the main parameters. It is recommended to use a UART-USB converter to connect drivers to a computer.

SMD‑1.6mini ver.2 drivers are supplied complete with motors SM4247.
