ESMC-02 programmable stepper motor controller with microstepping of full, half, quarter and eigth step. Complete with superb quality astrosyn MY702 size 23 hybrid stepper motor with 6.35mm round shaft with D cut. Final price is inclusive of VAT.

Simple to use, robust, powerful and reliable. The ESMC-02 moves the motor smoothly and efficiently.

This PCB operates in three main modes;

1.Push button operation. Just connect pushbuttons for clockwise and anticlockwise with speed controlled by an on-board pot.

2.Programmable control, set the number of steps in each direction (stored in onboard EEPROM) each press will then step the motor the amount programmed with or without overrun.

3.Direct inputs for step, direction, sleep and enable direct to the stepper motor driver IC

Operates from 7.5V DC to 30V DC with adjustable motor current up to 750 mA

The motor is rated at 8.68 Volts with the motor coils in series, but it is normal practise to run the motor at a significantly higher voltage and this set-up will work happily at, for example, 20V
