Designer Systems DS-STX4.S 4 Channel Stepper Motor Driver Shield (I2C)

A 4-channel unipolar stepper motor driver with advanced control features that is ideal for use with the Raspberry Pi and Arduino UNO systems. The shield features high speed I²C communication for easy project integration and smooth speed control.

Each connected stepper motor can be stepped in either direction a specific number of steps, continually stepped, stopped with a holding torque or completely off. Variable speed control is possible and the driver supports all 5 to 12V unipolar (5-wire ) stepper motors.

• Arduino UNO shield standard form factor
• Supports all Arduino boards
• Frees up I/O lines normally used for motor control
• On board 3A 5V regulator can be used to control external power supplies for motors
• 8-bit speed control gives 1 to 255 levels of control for each motor
• 16-bit step control gives 1 to 65,535 levels of step control for each motor
• Movement complete status for each motor
• Global activation control ensures all motors start together
• I²C address links allow up to 4x shields to be used together
