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.
The S05NF mini servo motor has dimensions of 28.8 x 13.8 x 30.2mm. The operating voltage for this motor ranges between 4.8 to 6V with a maximum rotation of roughly 180 degrees. This servo motor comes with the servo horns and related hardware components.
This gearmotor is a compact (1.50″ x 0.59″ x 0.47″) brushed DC motor with 35: 1 metal gearbox. These units have a 0.365″-long, 3 mm-diameter D-shaped output shaft that matches the micro metal gearmotor output shafts.
This NEMA 17 size bipolar stepping motor has a 0.9 Degree step angle (400 steps/revolution). Each phase draws 1.7 mA at 3 V, allowing for a holding torque of 4.9 kg-cm (68 oz-in).
This small NEMA 8-size hybrid bipolar stepping motor has a 1.8 Degree step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). With a weight of 60 g, this is one of the smallest stepper motors we carry.
