[vc_row][vc_column width=”1/1″][vc_column_text]The Motor Shield is a perfect platform for robotics and mechanical applications. It enables the Arduino/pcDuino to drive two brushed DC motors or one 4-wire two-phase stepper motor. So with this motor shield, we can build up our own pcDuino-powered intelligent vehicle or other robots.
Product page of this motor shield please check out here.[/vc_column_text][vc_tour][vc_tab title=”Parts List” tab_id=”1388037519-1-85″][vc_column_text]Motor shield x1
