Le MotorShield Controller est une carte d'actionneur conçue pour piloter deux moteurs DC. Elle intègre des circuits en pont en H et des capteurs de courant basés sur des résistances shunt, permettant la détection d'événements, la protection contre les surintensités, le contrôle PWM, ainsi que l'indication visuelle de la direction de rotation des moteurs.
