DS-STX4.S

  • The STX4.S is a four channel stepper motor driver for the Arduino, Raspberry-Pi or any other I2C bus platform. The driver supports Unipolar stepper motors of 5-12VDC and 500mA per phase and has an onboard 5V @ 3Amp regulator to provide a 5V power output to power a connected Arduino or Raspberry-Pi platform. Up to four boards can be connected to the same platform to provide a maximum of 16 channels.

Description

The Designer Systems DS-STX4.S is a four [4] channel 5V or 5-12V (jumper selectable) Unipolar stepper motor driver with advanced control features.
Specifically targeted at the Arduino UNO board user [all other Arduino boards supported] and the Raspberry-PI the STX4.S features high speed I2C communication for easy project integration and smooth speed control.
Once connected each stepper motor can be stepped in either direction a number of steps (with speed control), continually stepped (with speed control), stopped (with holding torque or completely off ), with selectable 1 or 2 phase excitation, by simply writing a value to an internal register over the connected I2C interface.
The STX4.S supports all 5-12V unipolar (5 wire) stepper motors (with a minimum winding resistance of 20R [250mA]) and also provides global activation of new stepper positions & movement complete registers for superior control.
The STX4.S provides a high power regulator capable of sup-plying 5V @ 3A to the connected servos from an external Li-Pol or Ni-MH battery pack of 7.2 to 8.4V and a 5V @ 1A USB A power output to power an externally connected Arduino board or Raspberry-Pi. Alternatively a jumper selection allows servos with a maximum 12V operating voltage to be used.
The on-board I2C pull-ups are jumper configurable to allow disconnection when connecting to the Raspberry-PI, which has its own pull-ups.

Features

  • Arduino UNO Shield standard form factor for simple integration into any Arduino project.
  • I2C interface for simple connection to Arduino or Raspberry-PI.
  • On-board 5Volt 3Amp regulator, with heat-sinking, for stepper motor and external 5V supply.
  • 255 level step speed control for each motor.
  • 16bit (1 to 65535) number of steps control for each motor.
  • I2C address links allow up to four [4] shields to be used together to provide up to 16 servos.
  • Movement complete complete status for each motor.
  • Global activation control ensures all motors start moving together, important for 2/4 wheel drive rovers.
