Arduino Motor Shield (L298N) (SKU:DRI0009)

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 6. The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7.

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.

Logic Control Voltage：5V (From Arduino)

Motor Driven Voltage：4.8～35V (From Arduino or External Power Source)

Logic supply current Iss：≤36mA

Motor Driven current Io：≤2A

Maximum power consumption：25W（T=75℃）

PWM、PLL Speed control mode

Control signal level:

High：2.3V≤Vin≤5V

Low：-0.3V≤Vin≤1.5V

Motor Shield

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.

Control Mode Selection Jumpers Motor Terminal: Two DC motors are connected to blue motor terminals. The male header behide the terminals are the same as the motor terminals. Motor terminal PWRIN： 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.
