Introduction

This motor shield allows Arduino to drive two channel DC motors. It uses a L298N chip which deliveries output current up to 2A each channel. The speed control is achieved through conventional PWM which can be obtained from Arduino’s PWM output Pin 5 and The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and The Motor shield can be powered directly from Arduino or from external power source. It is strongly encouraged to use external power supply to power the motor shield.

IOREF pin for Version

The board's IOREF pin is connected with pin 5V! So when adding the DRI0009 to the stack of board controller , the controller's supply voltage would changed to 5V! So it only can be compatible with the controller working at 5V. If you need to use controller working at other voltage, e.g. 3.3V, you need CUT OFF the IOREF pin of DRI0009.

PinOut

Control Mode Selection Jumpers:

The shield supports PWM and PLL Phased Locked Loop control Modes. The PWM mode uses E1 and E2 to generate PWM signal. The PLL mode uses M1 and M2 to generate phase control signal.

Motor Terminal Two DC motors are connected to blue motor terminals. The male header behide the terminals are the same as the motor terminals.

The motors can be powered by external power supply when the motor current exceeds the limits provided from the Arduino. The swith between external and Arduino power is implemented by two jumpers.
• PWRIN External Power
• VIN Arduino Power
