This motor driver shield can drive up to 4 DC motor with 2 servo motors or 2 stepper motors with 2 servo motors. This motor driver shield uses 2x L293D motor controller chip with a 74HC595 shift register for all of its functions.
This 1.46″ x 0.79″ x 0.79″ gearmotor is a brushed DC motor with 65: 1 metal gearbox that has the power to deliver both speed and torque. These units have a 0.276″-long, 4 mm-diameter D-shaped output shaft.
This 2.05″ ?1.45″ ?1.45″gearmotor is a powerful brushed DC motor with metal gearbox intended for operation at 12 V. These units have a 0.61″-long, 6 mm-diameter D-shaped output shaft.
This 1.46″ x 0.79″ x 0.79″ gearmotor is a brushed DC motor with 120: 1 metal gearbox that has the power to deliver both speed and torque. These units have a 0.276″-long, 4 mm-diameter D-shaped output shaft.
This shield makes it easy to build an Arduino-controlled Zumo robot. The shield mounts onto an assembled Zumo chassis, connecting directly to the chassis s battery terminals and motors, and the Arduino plugs into the shield, face down. The shield includes dual motor drivers, a buzzer for playing simple sounds and music, a user pushbutton, and a 3-axis accelerometer and compass. It boosts the battery voltage to power the Arduino, and it breaks out the Arduino I/O lines, reset button, and user LED for convenient access and to accommodate additional sensors for things like obstacle and edge detection.
