The Motor Protector is based on the L298, which is a dual complete bridge controller designed to handle inductive loads such as relays,
solenoids, DC and steps motors He passed.allows you to drive two CONTINUOUS CURRENT motors with your Arduino board, controlling the speed and direction of each independently.it is also possible to measure the current consumption of the motor of each motor, among other characteristics.the shield is TinkerKit compatible,
which means you can quickly create projects by connecting TinkerKit modules to the board.
-Operating Voltage: 5V ~ 12V
– Motor controller: L298P, units of 2 motors of CONTINUOUS CURRENT or stepper motor 1
– maximum current: 2A per channel or 4A max (with external power supply)
– current detection: 1.65 V / A
running non-stop and brake function?
the Motor Protector must be powered only by an external power supply.
because the L298 IC mounted on the shield has two separate power connections,
one for the logic and one for the motor power conductor.the required motor current often exceeds the current maximum USB rating.
External (non-USB) power can come from an AC to DC (wall-wart) adapter or battery.
the adapter can be connected when connecting a center-positive 2.1mm plug into the Arduino board for power socket from
which the motor protector is mounted or by connecting the cables that direct the power supply to the Vin and GND screw terminals,
being careful to respect the polarities.
To avoid possible damage to the Arduino plate for the shield to be mounted, it
is recommended to use an external power supply that provides a voltage between 7 and 12 V.
If your motor requires more than 9 V we recommend that you separate the power lines from the screen and the Arduino plate so
that the shield is mounted.this is possible by reducing the “Vin Connect” bridge placed on the back of the shield.
the absolute limit for the Vin on the screw terminals is 18 V.
The power pins are as follows:
Vin in the screw terminal block is the input voltage for the motor connected to the shield.
An external power supply connected to this pin also provide power to the Arduino board for it to be mounted.
cutting the bridge “Vin Conexion” that make this a power line exclusive to the engine.
GND Ground in the screw terminal block.
the shield can provide 2 amps per channel, for a total of 4 amps maximum.
on input and output voltage:
this shield has two separate channels, flame A and B, which each use 4 of the for Arduino pins for or motor sense.
in total there are 8 pins in the use of this shield.
you can use each channel separately to drive two CONTINUOUS CURRENT motors or combine them to drive a unipolar stepper motor.
pins of the shield, divided by the channel are shown in the following table:
pins by Channel.one
pins per channel.B
If you do not need the Brake and Current Detection and also need more pins for your application you can disable this account by reducing the respective jumpers on the back of the shield.
the additional shots on the shield are described as follows:
screw terminal to connect the motors and their power supply.
2 TinkerKit connectors for two Analog Inputs (blank), connected to A2 and A3
2 TinkerKit connectors for two Aanlog Outputs (in orange in the middle), connected to PWM outputs on pins D5 and D6.
2 TinkerKit connectors for the TWI interface (blank with 4 pins), one input and one output.
brushed motor of CONTINUOUS CURRENT.you can drive two DC motors by brushing two cables each on the ( ) and (-) screw terminals for each channel A and B. This way you can control your direction by setting HIGH or LOW the A and DIR DIR B pins, you can control the speed by varying the PWM A and duty cycle PWM B values.the Brake One and Brake B pins, if HIGH, will effectively brake the CONTINUOUS CURRENT engines instead of letting them slow down by cutting off the power.you can measure the current passing through the current motor CONTINUE READING the pins SNS0 and SNS1.in each channel will be a voltage proportional to the measured current, which can be read as a normal analog input,
