RobotDyn Motor Shield 2A L298P 2-motors for Arduino

Motor Shield 2A for Arduino allows to control of 2 DC-motors, to control rotational speed, rotational direction, to stop motors with freewheeling or to block their action. You can control each motor. Also you may drive bipolar step motor current up to 4A.

Motor Shield 2A for Arduino is based on L298P chip with voltage 5-36V and peak current up to 2A on each motor (channel). It can be installed on Arduino: Uno, Duemilanove and Mega.

Shield has LED indicating rotational direction of each motor.

Speed regulation is realized through PWM default mode, signal can be applied by PWM Arduino outputs 10 and 11 (digital outputs complying PWM).

It has 2 modes of rotational control:

Direct control: Motor 1 - outputs: 8, 9, 10(PWM)/ Motor 2 - outputs: 11(PWM), 12, 13;

Logic control: Motor 1 - outputs: 9, 10(PWM)/ Motor 2 - outputs: 11(PWM), 13.

Use shield switches to change control mode. There is individual switch for each channel.

Direct regulation provides control of L298P driver and use 3 Arduino outputs for each channel.

Using logic regulation give free digital Arduino outputs: 8 and 12.  And used only 4 digital outputs.

Motor control tab:

	Pin#	Logics on				Logics off
		Forward	Back	Free stop	Stop block	Forward	Back	Free stop	Stop block
Motor 1	10-E1	1	1	0	Not available	1	1	0	1
	9-In1	0	1	0/1		1	0	0/1	1
	8-In2	Not used				0	1	0/1	1
Motor 2	11-E2	1	1	0		1	1	0	1
	13-In3	0	1	0/1		0	1	0/1	1
	12-In4	Not used				1	0	0/1	1

* 0 = LOW, 1 = HIGH.

Shield can be powered with Arduino Vin (6-12V)or external supple (5-36V). Use jumper to switch power source.
