L298 MODULE
Description
This is a low cost motor controller.
Although it’s not an Arduino Shield, it can be used with Arduino or any other microcontroller platforms.
This module allows you to connect 2 DC motors and have total control of them from the arduino.
It also can be used to control one 4-wire stepper motor.
Due to its high current rating, it’s perfect for a single channel heavy duty stepper motor controller.
It allows you to move each DC motor
– Clockwise
– AntiClockwise
– Stall
– Control motor speed
A 4-way stripped wire is included.
This motor controller uses a L298 H-bridge IC deliveries output current up to 2 A each channel.
The speed control is achieved through conventional PWM which can be obtained from Arduinos PWM output Pin 5, 6, 9 and 10.
Specifications
Peak Output Current (each Channel)
– Non Repetitive (t = 100 ms): 3 A
-Repetitive (80% on -20% off; ton = 10 ms): 2.5 A
-DC Operation: 2 A
Analog voltage input:
Vcc input:
7 – 35 V with jumper J3 short circuit, which gets regulated to 5 V and it’s available on the +5 V terminal.
5 – 35 V with jumper J3 open circuit, a seperate 5 V input is needed to the +5 V terminal.
Digital voltage input: VD = 5 V (7 V max), this is output 5 V when jumper J3 is short circuit,
and input 5 V when J3 is open circuit.
Max power dissipation: 20 W
There is a voltage regulator that regulates the Vcc to 5 V for digital use.
Dimensions (L x B x H): 43 x 43 x 27 mm
