Barcode Formats: EAN-13 7630049200371
Manufacturer: Arduino
Description:   The Arduino Motor Shield is based on the L298 (datasheet) which is a dual fullbridge 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. The shield is TinkerKit compatible which means you can quickly create projects by plugging TinkerKit modules to the board. The Arduino Motor Shield is opensource hardware! You can build your own board using the following files see document tab above. The Arduino Motor Shield 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 supply driver. The required motor current often exceeds the maximum USB current rating.External (nonUSB) power can come either from an ACtoDC adapter (wallwart) or battery. The adapter can be connected by plugging a 2.1mm centerpositive 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 reccomend 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. The power pins are as follows: Vin on the screw terminal block is the input voltage to the motor connected to the shield. An external power supply connected to this pin also provide power to the Arduino board on which is mounted. By cutting the Vin Connect jumper you make this a dedicated power line for the motor. GND Ground on the screw terminal block. The shield can supply 2 amperes per channel for a total of 4 amperes maximum. Input and Output This shield has two separate channels called A and B that each use 4 of the Arduino pins to drive or sense the motor. In total there are 8 pins in use on this shield. You can use each channel separately to drive two DC motors or combine them to drive one bipolar stepper motor. The shield s pins divided by channel are shown in the table below: Function pins per Ch. A pins per Ch. B Direction D12 D13 PWM D3 D11 Brake D9 D8 Current Sensing A0 A1 If you don t need the Brake and the Current Sensing and you also need more pins for your application you can disable this features by cutting the respective jumpers on the back side of the shield. The additional sockets on the shield are described as follow: Screw terminal to connect the motors and their power supply.
Features:
  • Control speed and direction for two DC motors, or just speed with four DC motors; drive a large stepper motor up to NEMA 17.
  • Connect other sensors and actuators through the shield’s Molex connectors.
  • Connect more to your board! It works also for up to four (external) relays or solenoids.
  • Works with your Arduino Uno, Uno SMD, Mega, and Leonardo.
  • External power input to separate the motor power from the microcontroller one.
