Key features
  • Operating voltage: 8 V - 45 V DC
  • 7 A peak ouotput current (3 A rms) for each motor driver
  • Digital voltage supply is selectable (3.3 V or 5.0 V) by a 0 Ω resistor and is provided on main board
  • 3.3 V digital voltage supply may be provided by:
    • the STM32 Nucleo
      board
    • the step-down monolithic power switching
      regulator soldered on the expansion board (through jumper selection, it can also be
      used to supply the STM32 Nucleo board
  • USART communication
    • enables receiving of commands from a
      PC
    • enables sending information to a
      PC
    • Requires no dedicated cable; uses the Type A to
      Type Mini-B USB cable already used to supply the STM32 Nucleo
      board
  • SPI interface (may be connected in a daisy chain configuration)
  • Equipped with Arduino UNO R3 connectors
  • Layout compatible with ST morpho connectors
  • Five LEDs:
    • 2 green, to indicate that each L6470 is
      powered
    • 1 orange, to indicate that the digital voltage
      is on
    • 1 yellow, to indicate when any L6470 is
      busy
    • 1 red, to indicate when a fault condition occurs
      (step loss, OCD, thermal pre-warning or shutdown, UVLO, incorrect command,
      non-performable command) for any L6470
  • RoHS compliant
