Introduction
The Motor Shield is a perfect platform for robotics and mechanical applications. It enables the Arduino to drive two brushed DC motors or one 4-wire two-phase stepper motor. Based on the H-bridge driver Chip L298N motor driver integrated circuit, it requires a 6V to 15V power supply to power the motor and also includes an on-board 5V voltage regulator for powering the main Arduino board. Additional plug and play 2.54mm spacing Grove sensors can be connected to the 13 on-board Grove connectors.
Features
- Standard Arduino compatible
- Pulse-width modulated speed control mode
- 4 direction indicator lights
- Compatible with Linker Kit 2.54mm spacing Grove plug and play sensors
- Extra large heat sink helps handle big loads
- Supports up to 14 servos
