  • I²C bus, only 2 microcontroller lines are required
  • 8 independent channels, each 500mA (650mA peak)
  • Output can be paralleled
  • Controls 2 unipolar steppers 500mA/phase or 1 stepper 1000mA/phase
  • Selectable I²C address
  • Externally powered (50V max) or 5V from I²C header
  • Simple small single sided PCB
  • Based on cheap and popular ICs
