The module protects the load against reverse polarity to -60 V, but does not block reverse current, which is desirable in applications such as motor control. It uses the LM74500-Q1 controller and a MOSFET transistor. Thanks to its low impedance (10 mΩ), it supports currents up to 10 A continuous and 30 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5380

An H-bridge capable of controlling one DC motor in both directions or two unidirectional motors at voltages from 4.5 to 44 V and continuous current up to 1.1 A. The module offers three operating modes (PH/EN, IN/IN, half-bridge), built-in current limiting and measurement, and protection against overheating, overload, undervoltage, and reverse polarity. Its compact design, flexible logic power supply (1.8–5.5 V), and simple control make it ideal for robotics, automation, and hobby projects. Pololu 4972

Sub-micro analog servo with plastic gear. It has a range of motion of 180°. Pololu 1053

Ultrasonic distance sensor MB1000 with a range from 0 to 645 cm. It has an output in the form of a serial interface, an analog signal or generates an impulse whose duration is proportional to the measured distance. Pololu 723
