Product Overview

The ROHM-STEPMO_EVK_208 is a stepper motor driver evaluation kit. It is a low-cost board enabling fast evaluation of ROHM stepper motor BD63847EFV IC and easy prototyping of real applications. The kit consists of a stackable shield for Arduino Uno board and a software library to manage the stepper motor driver IC. The EVK can be used as well standalone providing power supply and appropriated input signals. This EVK supports microstep, high voltage with CLK-IN (clock input) control stepper motor driver BD63847EFV IC. It integrates PWM constant-current drive with adjustable decay ratio and the ability for full, half and microstepping. The IC features single supply operation by integrating voltage regulator for the low power logic together with highly efficient DMOS output power stages. The motor driver integrates ghost supply prevention, thermal shutdown, overcurrent protection, under/overvoltage lockout high ESD resistance and pin short protection for robust and reliable operation.
  • Supply voltage range from 19V to 28V
  • Maximum current per phase is 2A at 25°C
  • Supports 1, 1/2, 1/8, 1/16 stepping modes
  • Designed as plug-in shield for Arduino platform
  • Adjustable current decay mode
  • Stackable design to allow controlling two motors at the same time
  • Reverse power supply protection
  • Do not require an internal charge pump so the motor drivers achieve low EMI performance
  • CE marked


Motor Drive & Control


This EVK is only to be used as device under test for research and development purposes and only to be operated by trained professionals.
