Arduino Motor Shield Rev 3

On Arrival Arduino Motor Shield Rev 3

More info :

The Arduino Motor Shield is based on the L298, which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors.
It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features.

Description:

  • Operating Voltage: 5V ∼ 12V
  • L298P Motor controller (drives 2 DC motors or 1 stepper motor)
  • 2x power channel: 2A per channel or 4A max current (with external power supply)
  • Current sensing: 1.65V/A
  • Free running stop and brake function
  • 1.0 standard pinout
  • 2x TWI (I2C) 4 pins connectors (use TinkerKit connectors or female jumpers)
  • 1x 2 pins connectors connected to A2 and A3 (use TinkerKit connectors or female jumpers)
  • 1x 2 pins connectors connected to D5 and D6 (use TinkerKit connectors or female jumpers)

 

Pinout:

Function pins per Ch. A pins per Ch. B
Direction D12 D13
PWM D3 D11
Brake D9 D8
Current Sensing A0 A1

 

 

 

 

 

Power connections:

The Arduino Motor Shield must be powered only by an external power supply, or you may damage your microcontroller board.

Power pins:

Description Function Remarks
Screw Terminal (Vin - GND) External Power (battery) Connected to Arduino Vin pin
Screw Terminal (A) Power output for motor A  
Screw Terminal (B) Power output for motor B  

 

 

 

 

 

 

External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the Arduino's board power jack on which the motor shield is mounted or by connecting the wires that lead the power supply to the Vin and GND screw terminals, taking care to respect the polarities.

To avoid possible damage to the Arduino board on which the shield is mounted, we recommend using an external power supply that provides a voltage between 7 and 12V. If your motor require more than 9V we recommend that you separate the power lines of the shield and the Arduino board on which the shield is mounted. This is possible by cutting the "Vin Connect" jumper placed on the back side of the shield. The absolute limit for the Vin at the screw terminals is 18V.
