ROHM Stepper Motor Driver Shield for Arduino Platform
Enables fast evaluation and prototyping with ROHM Stepper Motor ICs
ROHM's Stepper Motor Driver Evaluation Kit (ROHM-STEPMO_EVK_20x) is a low-cost board enabling fast evaluation of ROHM Stepper Motor ICs 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 a variety of pin-compatible ROHM stepper motor driver ICs (see table below) from standard, microstep, low voltage and high voltage families with CLK-IN (clock input) or PARA-IN (parallel input) control. They integrate PWM constant-current drive with adjustable decay ratio and the ability for full, half and microstepping. The ICs feature single supply operation by integrating the voltage regulator for the low power logic together with highly efficient DMOS output power stages.
