![]() ![]() Connecting the battery in reverse polarity will damage the motor driver instantaneously. ![]() Note: Power input does not have reverse-voltage protection. This way, SHIELD-MDD10 is able to deliver its full potential depending on the actual condition without damaging the MOSFETs. The higher the board temperature, the lower the current limiting threshold. When the motor is trying to draw current more than what the motor driver can support, the motor current will be limited at the maximum threshold.Īssisted by temperature protection, the maximum current limiting threshold is determined by the board temperature. Overcurrent protection prevents the motor driver from damage when the motor stalls or an oversized motor is hooked up. Various protection features are also incorporated in the SHIELD-MDD10. If the specified pins on Arduino are already used up by other application/shield, you can select another pin easily with the jumper. The Arduino pins for these inputs are configurable via jumpers. This motor driver can be controlled with PWM and DIR inputs. This eliminates the need of extra power supply for the Arduino mainboard. Buck regulator which produces 5V output is also available to power the Arduino mainboard. The onboard test buttons and motor output LEDs allow functional test of the motor driver in a quick and convenient way. The Arduino Motor Shield is based on the L298 (datasheet). With discrete NMOS H-Bridge design, this motor driver is able to support 10 Amp per channel continuously without any additional heatsink. The Arduino Motor Shield allows your arduino to drive DC and stepper motors, relays and solenoids. It is able to control two brushed DC motors or single bipolar/unipolar stepper motor from 7V to 30V.
