3A Open Drain and
unipolar Stepper motor controller board
In
domotic applications is frequently required interfacing with
Relays for driving loads or even turn on lights or sirens.
In these applications the Open Drain board is particularly useful. The usage of 4 power MOSFET and the Drain protection from inductive loads, let this board being used for driving unipolar stepper motors up to 3A. The board is designed to be compatible with Freedom.
