Introduction

The Motor Shield V1.0 is a platform for robotics and mechanical applications based on L298P. It can be used to drive double DC motor or a 4-wire stepper. When controlling double DC motor, there are Only 4 control pins were been used, which makes more easily to control, and saves the control pins for controller. The Drive current can be up to 2A per motor output for the add of the heat sink. Measure the driver current by the additional resistance, makes the system more smarter.

Technical Data
