The GSM2 is a standalone drive board designed to drive a stepper motor in unipolar mode. It is done either with or without forcing resistors connected between motor commons and supply voltage.
When using the logic connections, you are able to select full, half or wave mode and direction and speed external clock. The GSM2 drive board allows an enable and disable input for various start/stop control options.
Compatible with any four phase unipolar stepper motors up to 2A/40Vdc per phase with full, half and wave modes able to selected.
Please note: The stepper motor used with the board must have four phases and five, six or eight wires.
